DRESS CODE: FORMAL OR BLACK TIE OPTIONAL ATTIRE FOR WOMEN AND MEN

The Formal or Black Tie Optional dress code sits gracefully between Semi-Formal and Black Tie attire. It carries the refined spirit of a formal affair but allows guests a touch more freedom in how they express it. In essence, it means exactly what it says — the event is formal enough to call for a full black tie (a tuxedo, floor-length gown, and elegant accessories), yet wearing one is not mandatory.

Think of it as a celebration of elegance with a whisper of flexibility. The hosts are envisioning an evening of polished sophistication — impeccably dressed men, the soft shimmer of luxurious fabrics, and an atmosphere that feels elevated yet welcoming. Black tie optional invites you to dress up and shine, without the rigid rules of a traditional black tie affair.

Formal dress codes encompass the full spectrum of attire designed for high-end events: dramatic colors, flowing silhouettes, and the kind of gowns that make a graceful entrance. If you’re ever unsure, a foolproof choice is an ankle-grazing dress paired with statement jewelry — timeless, confident, and effortlessly appropriate.

1. What Is Formal or also called Black-Tie Optional Attire?

Among all dress codes, Black Tie Optional—sometimes also referred to as Formal Attire—might be the most confusing phrase to appear on an invitation. It sounds elegant, it feels important, and yet the word optional throws even the most confident dresser into a moment of hesitation. What exactly is being “optional” here? The tie? The tuxedo? The stress?

Let’s start by decoding what hosts really mean.

When an invitation says Black Tie Optional, it signals that the event is formal—think evening elegance, polished sophistication, and timeless refinement—but that guests are not required to wear a tuxedo or a full-length ball gown. The host hopes for the look and atmosphere of a black-tie event but wishes to keep the experience inclusive, flexible, and kind to guests who may not own a tuxedo or couture-level gown.

In essence, it’s a gesture of grace and practicality. The couple or host wants their celebration or gala to feel special, while understanding that formalwear can be an investment. You’re invited to dress up to your most elegant comfort level—ideally leaning toward tuxedos, floor-length dresses, or refined suits and gowns, but not strictly confined to them.

As fashion stylist Anny Choi explains, “Black Tie Optional means the couple does want black tie, but doesn’t want to pressure guests into tuxedos and evening gowns since those tend to be more of an investment.” It’s an invitation to rise to the occasion rather than a demand to meet an unyielding code.

For women, that might mean a sophisticated floor-length gown or a beautifully tailored cocktail dress in a formal fabric. For men, it’s either a tuxedo or a dark, well-tailored suit with a tie. The key is effort. This dress code rewards those who show intentionality—whether that’s choosing polished accessories, well-fitted tailoring, or an elegant hairstyle that completes the look.

So, if you receive an invitation labeled Formal or Black Tie Optional, know that it’s your chance to embrace an elevated look that still allows space for personality. It’s formal without the fuss, glamorous without the rigidity, and all about expressing respect—for the hosts, the moment, and yourself.

2. Black Tie Optional vs. Black Tie vs. White Tie – What’s the Difference?

Before we go further, let’s clear the haze around the trio that often trips up even seasoned event-goers: Black Tie Optional, Black Tie, and White Tie.

Each term signals a different level of formality—a kind of fashion hierarchy of refinement. Understanding their distinctions not only helps you dress appropriately but also ensures you feel perfectly at ease among fellow guests.

2. 1. White Tie – The Pinnacle of Formality

White Tie events are the most formal gatherings in modern Western dress culture. Think state dinners, royal banquets, or grand charity galas attended by diplomats.
For men, this means a black tailcoat with matching trousers (featuring satin stripes on the leg), a crisp white wing-collar shirt, white bow tie, white waistcoat, and black patent leather shoes. Every detail matters—from cufflinks to posture.
For women, White Tie typically calls for a full-length evening gown, often in luxurious fabrics like silk or satin, paired with long gloves, understated jewelry, and a classic updo. The mood is timeless grandeur; you are, quite literally, dressing for history.

2. 2. Black Tie – Classic Elegance with Clear Boundaries

Black Tie is formal eveningwear, codified in the 19th century and still the benchmark of sophisticated style today.
For men, this means a tuxedo (or dinner jacket) with satin lapels, a white dress shirt, black bow tie, black patent shoes, and minimal accessories. For women, the traditional choice is a floor-length evening gown, though in modern times, chic midi or high-end cocktail dresses can work, provided they are made of formal fabrics and styled appropriately.
The atmosphere is elegant, polished, and uniform. Everyone looks ready for a gala or red-carpet premiere.

2. 3. Black Tie Optional – Elegance with Flexibility

And then there’s our friend Black Tie Optional—a slightly more relaxed branch on the same tree of formality. Here, men may choose between a tuxedo and a dark suit (charcoal, black, or navy) paired with a conservative tie. Women have the freedom to select a floor-length gown, a refined cocktail dress, or dressy separates.

The goal is to maintain the overall tone of a formal event without obliging every guest to meet its strictest requirements. It’s a modern, inclusive interpretation of the traditional Black Tie concept—an acknowledgment that elegance can be achieved in more than one way.

So, while White Tie insists, Black Tie expects, and Cocktail allows—Black Tie Optional invites. It invites you to look your best within your comfort zone, to honor the occasion while retaining authenticity.

In short:

• White Tie = absolute formality, no deviations.
• Black Tie = formal elegance, defined rules.
• Black Tie Optional = formal, but with room for creative and budget-friendly expression.

Or as one Vogue editor humorously put it: “White Tie says ‘Your Majesty will see you now.’ Black Tie says ‘We’re celebrating something important.’ And Black Tie Optional says ‘We’d love it if you dressed up, but we won’t faint if you don’t own a tux.’”

3. Black Tie Optional – When to Wear It?

You’ll most often encounter the Black Tie Optional dress code at evening weddings, elegant galas, award dinners, and fundraising events—occasions where the hosts wish to preserve a sense of grandeur without imposing a rigid standard.

In essence, it’s the “best of both worlds” attire request: an evening that feels luxurious and memorable, yet approachable for everyone.

If you’re ever unsure whether a Formal or Black Tie Optional outfit is appropriate, consider the setting and timing:

• Evening weddings (after 5 PM) often favor this dress code.
• Upscale charity events or corporate awards nights may also list it.
• Festive seasonal celebrations, particularly around the holidays, are increasingly adopting the “optional” version for guests’ comfort.

So how do you respond to such an invitation? Lean in. This is your chance to express your most sophisticated self, without feeling boxed in by the rigidity of a tuxedo rental or a couture gown.

• If you’re a woman, think rich fabrics—silk, satin, velvet, chiffon—and elegant lines. Floor-length gowns are always appropriate, but a tastefully cut midi or knee-length dress can shine too, especially when styled with statement jewelry, polished heels, or an elegant clutch. If in doubt, dress up rather than down; it’s better to be slightly overdressed than risk looking casual.
• If you’re a man, the simplest answer is: wear a tuxedo if you have one, but a dark, well-tailored suit with a crisp white shirt and a conservative tie is equally acceptable. What matters most is the fit, the finish, and the respect your outfit conveys for the event.

The phrase “Black Tie Optional” might tempt some to underdress—but here’s the truth: the optional applies to the tuxedo, not to the formality. It’s an opportunity to rise to the occasion, not to step away from it.

And if you’re still unsure, consider this gentle rule of thumb:

• If you wonder whether it’s too formal, it’s probably just right.
• If you wonder whether it’s too casual, it probably is.

4. Formal or Black Tie Optional Attire for Women

There’s a certain kind of magic in a Black Tie Optional invitation. It invites you to be elegant without dictating exactly how. It’s the space between formal and free — where sophistication meets personal expression. For women, this dress code is an opportunity to embrace refined glamour, whether through a classic gown, a tailored jumpsuit, or a modern evening suit. The goal is to look poised, polished, and intentional — never overdressed, yet always appropriate. Think of it as your permission to interpret “black tie” through your own graceful lens.

4. 1. Formal or Black Tie Optional Attire for Women – What to Wear

When the invitation reads Black Tie Optional, think of it as an elegant wink. It’s formal—but not fussy. You’re expected to rise to the occasion, but allowed to do it in your own way. This is where your personal sense of grace meets a touch of Hollywood polish.

Here’s your guide to balancing that refined poise with your own authentic flair.

4. 1. 1. Two-Piece Suits and Jumpsuits

While gowns will always hold the spotlight, today’s women know that confidence wears many forms. A well-tailored two-piece suit or a structured jumpsuit can look just as commanding as a dress—especially when the fit is impeccable. Think clean lines, luxurious fabrics, and silhouettes that elongate rather than overwhelm.

For suits, lean into dark hues like navy, black, deep emerald, or even a soft metallic for evening. Add a silk camisole underneath and delicate jewelry for balance.
For jumpsuits, satin or crepe fabrics are your friends. Wide-leg cuts, one-shoulder details, or belted waists elevate your look instantly.

StyleUp tip: Before choosing a jumpsuit or suit cut, peek at your body shape profile through StyleUp’s Body Type Guide—it helps you pick the silhouettes that truly celebrate your form.

4. 1. 2. Jackets

A jacket can transform an outfit from “dinner out” to “black-tie ready.” Choose a blazer or cropped evening jacket in a fabric that mirrors your outfit’s formality—velvet, satin, or embellished crepe. Metallic threading, clean tailoring, or a subtle sheen give that perfect note of occasion without crossing into excess.

4. 1. 3. Blouses

If you’re wearing separates, your blouse should speak the language of sophistication. Silk, satin, or chiffon are ideal. High necklines, pussy-bow ties, or off-shoulder cuts all work beautifully, depending on your chosen bottom. Avoid overly casual fabrics like cotton poplin or linen—they simply whisper when the event calls for an elegant statement.

4. 1. 4. Skirts

Formal skirts are a marvelous way to express both femininity and power. A midi-length satin or taffeta skirt paired with an elegant blouse feels effortlessly timeless. Pleated or A-line silhouettes are universally flattering, and darker tones—black, plum, navy, or metallic—give that evening elegance with ease.
Avoid casual shapes like denim, cotton, or jersey skirts, which dilute the formality of the ensemble.

4. 1. 5. Dresses

This is the most traditional and intuitive option. A floor-length gown will always align perfectly with the Black Tie Optional standard. Yet, for more relaxed settings—or summer weddings—a refined midi or below-the-knee cocktail dress can be equally appropriate if styled thoughtfully.

Choose luxurious fabrics such as satin, silk, chiffon, or velvet. Keep prints subtle and colors rich—navy, emerald, burgundy, silver, or black never miss.
Cut and fit matter most: aim for structure, polish, and intentionality. Think of it this way—your dress should feel like it belongs in candlelight.

4. 1. 6. Pants

Elegant trousers can be surprisingly formal when cut and styled correctly. High-waisted wide-leg pants in silk-blend fabrics, paired with a satin blouse or structured corset top, can rival any gown in sophistication.
Finish the look with heels that add height and an evening clutch to anchor the outfit.

4. 1. 7. Shoes

Shoes are the punctuation mark of your outfit—choose wisely.
Classic pumps or strappy heels in black, metallic, or jewel tones are ideal. If heels aren’t your best friend, embellished flats or sleek pointed loafers can look equally chic (and mercifully comfortable). Just avoid casual sandals, wedges, or anything too chunky.

StyleUp reminder: Opt for comfort that doesn’t compromise grace—dancing the night away is always more fun when your shoes agree.

4. 1. 8. Accessories

Accessories are where your personality gets to whisper, “Yes, I belong here.”
Think statement earrings, a refined bracelet, or a timeless clutch. Choose one or two standout pieces—never all at once. Metallic accents, pearls, or crystal details pair beautifully with the evening glow.

A small evening bag or clutch is the perfect final touch; oversized totes belong firmly in daylight.

4. 1. 9. Makeup & Hair

Your makeup should complement the event’s formality while reflecting you.
Soft glam—defined eyes, luminous skin, and a confident lip—works beautifully. For hair, classic updos, smooth waves, or sleek ponytails are ideal. Messy buns or overly casual styles can undercut your refined look.

And remember: elegance doesn’t shout—it glows.

4. 1. 10. Pantyhose & Ties

Pantyhose aren’t mandatory but can add polish, particularly in cooler weather or ultra-formal settings. Sheer black or nude tones work best.
And if you’re one for androgynous style, feel free to add a silk tie or bow-tie moment with a tux-inspired outfit—it’s unexpected, daring, and utterly chic.

StyleUp Insight: Building a capsule wardrobe for formal events saves time, money, and last-minute stress—and lets you focus on enjoying the evening, not second-guessing your outfit.

4. 3. Shopping List for Dress Code Black Tie Optional – Women

• Floor-length gown (silk, satin, velvet, or chiffon)
• Formal midi dress
• Jumpsuit in satin or crepe
• Dressy blazer or bolero
• Satin blouse or camisole
• Wide-leg tailored trousers
• Classic pumps or strappy heels
• Embellished clutch
• Statement jewelry (1–2 pieces only)
• Evening-appropriate outerwear (shawl, wrap, or tailored coat)

Optional, but Elevating:

• Long silk gloves for an extra dose of retro elegance
• A hair accessory with crystals or pearls
• A wrap in cashmere or satin for chilly evenings
• A touch of shimmer in your eye makeup or accessories
• A delicate perfume with a sophisticated evening note
• These aren’t essential—but they turn a “nice outfit” into a “who is she?” moment.

4. 4. Black Tie Optional Attire for Women – What to Avoid

• Daytime dresses in cotton, linen, or casual prints. 
• Short mini dresses or anything too revealing, too colorful, and too flashy
• Chunky or casual footwear, including sneakers, flip-flops, or raffia wedges
• Oversized handbags or work totes
• Heavy daytime makeup or beachy hairstyles
• Funky T-shirts, sport jackets, khaki, or denim.
• In daytime, avoid very high heels or evening-style shoes.

In short: avoid anything that feels “daytime” or “casual.” Elegance is about intentionality. You want your outfit to say, I dressed for the occasion—not, I came straight from brunch.

5. Formal or Black Tie Optional Attire for Men

Between Tuxedo and Suit – The Essence of “Optional” Elegance

For men, black tie optional can feel like a phrase designed to confuse — yet in reality, it’s a generous invitation. It means you are welcome (and even encouraged) to wear a tuxedo, but you will be perfectly appropriate in a dark, well-tailored suit too. The word optional simply gives you the freedom to adapt your outfit to your wardrobe, comfort, and budget — without sacrificing formality or respect for the event.

A man attending a black tie optional event should always aim for a polished, refined appearance — something that would not look out of place among tuxedos, yet still feels authentically his own. This is not the time for casual blazers or business suits; rather, think in terms of your most elegant evening attire, tailored to perfection and styled with intention.

5. 1. Formal or Black Tie Optional Attire for Men — What to Wear

5. 1. 1. Tuxedo – The Classic Choice

If you own a tuxedo, or have access to one, wearing it is always the safest and most sophisticated option. A classic black tuxedo with satin or grosgrain lapels, a crisp white dress shirt, a black bow tie, and polished black patent leather shoes together create a look that commands quiet confidence.

You can personalize the ensemble subtly — for example, with cufflinks that reflect your style, a pocket square in a muted tone, or velvet loafers instead of patent Oxfords for a softer, modern finish. Remember: black tie optional doesn’t forbid full formality; it simply doesn’t demand it.

5. 1. 2. Dark Suit – The Modern Alternative

If a tuxedo feels too formal or unnecessary, a dark, impeccably fitted suit is your next best friend. Opt for black, charcoal, or midnight navy — these colors naturally carry evening sophistication. Pair it with a white dress shirt (never colored or patterned), a dark silk tie, and well-polished black shoes.

To elevate the suit closer to tuxedo territory, choose refined fabrics — lightweight wool or a subtle sheen, like a mohair blend, adds depth. Details matter: a silk pocket square, a slim tie bar, or sleek cufflinks can lend a sense of occasion without tipping into excess.

If the event leans more festive — for example, a winter wedding or a holiday gala — a velvet blazer or patterned dinner jacket can add tasteful flair. Think of it as optional luxury: a way to show personality within the boundaries of sophistication.

5. 1. 3. Shirts, Ties, and Accessories

White remains the gold standard for shirts at black tie optional events. It conveys crispness, formality, and contrast. If you prefer a more relaxed but still elegant feel, a light ivory or pale dove-gray shirt can work in softer lighting.

As for ties — keep them silk, solid, and dark. A black tie or midnight blue tie echoes the tuxedo palette beautifully. Bow ties are also appropriate even without a tuxedo, especially in textured silk or subtle patterns.

Accessories should complement, not dominate. Choose cufflinks that are understated, a classic watch, and a neatly folded pocket square. Avoid overly trendy colors or loud prints; the overall mood is polished ease, not playful experimentation.

5. 1. 4. Footwear and Grooming

Shoes anchor the entire look — and at a black tie optional event, they must be formal. Polished black leather Oxfords, cap toes, or wholecuts are ideal. Patent shoes are perfectly acceptable with tuxedos but not required with suits. Loafers, if chosen, should be sleek and made from premium leather or velvet, never casual suede.

As always, immaculate grooming elevates everything. Neatly trimmed hair, clean nails, and a well-kept beard or smooth shave all reinforce respect for the formality of the occasion. If your attire is impeccable but grooming overlooked, the elegance is immediately diminished.

5. 2. Outfit Inspiration

A black tie optional outfit for men is about quiet confidence — it’s less about flash, more about finesse. Here are a few ways to interpret the dress code depending on the event and your personal style:

Classic Elegance:

Black tuxedo, crisp white pleated shirt, black bow tie, polished patent leather Oxfords, and a white pocket square. Timeless, effortless, and universally appropriate.

Modern Minimalist:

Charcoal gray wool suit with peak lapels, slim black silk tie, white shirt, black wholecut shoes, and a subtle silver tie bar. Sleek and contemporary, yet formal enough for any evening setting.

Creative Formal:

Midnight navy tuxedo jacket with satin lapels, black tailored trousers, open-collar white shirt, velvet loafers, and a patterned pocket square. Ideal for fashion-forward events or festive galas.

Winter Formal:

Black or dark green velvet dinner jacket, black wool trousers, white shirt, black bow tie, and polished leather loafers. Luxurious yet completely appropriate for cold-season occasions.

Tip: Before shopping, check your body shape guide from StyleUp’s Body Type Analyzer, which is also available for men. Knowing which cuts and silhouettes enhance your figure can make your outfit feel effortlessly “right".

5. 3. Shopping List for Dress Code Black Tie Optional – Men

If you’re building or upgrading your wardrobe for black tie optional events, these pieces will ensure you’re always ready — no matter how “optional” the formality might be:

• Tailored Dark Suit – In black, navy, or charcoal; ideally in high-quality wool or wool blend.
• White Dress Shirt – Crisp cotton or poplin with a structured collar.
• Silk Tie or Bow Tie – Black or dark-toned; a subtle texture (like ribbed or satin finish) adds depth.
• Tuxedo Jacket (optional but recommended) – Perfect for elevating your look instantly.
• Polished Formal Shoes – Black Oxfords, patent leather lace-ups, or velvet loafers.
• Cufflinks and Pocket Square – Small details that elevate your ensemble from business to formal.
• Dress Watch – Minimalist design in silver or black leather; avoid chunky or sporty styles.
• Quality Belt – Black leather with a simple, refined buckle.
• Velvet or Dinner Jacket (for special occasions) – Adds texture and festive charm.
• Grooming Essentials – Hair product, cologne, and a clean shave or well-kept beard.

When you invest in these timeless staples, you’re not just preparing for one event — you’re curating a lifelong capsule of evening elegance.

5. 4. Black Tie Optional Attire for Men – What to Avoid

Avoid light suits, casual fabrics, bright socks, sneakers, or anything that reads “office casual.” Even if the invitation says optional, the spirit of black tie remains. It’s not about relaxing the rules completely — it’s about allowing style within structure.

Skip T-shirts, sports watches, or novelty accessories. A black tie optional setting deserves refinement — not rebellion.

Summary – A Modern Gentleman’s Balance: A black tie optional dress code invites men to blend tradition with personal comfort — to honor formality without feeling constrained by it. Whether you choose a tuxedo or a refined dark suit, the goal remains the same: to look polished, poised, and appropriately elegant.

When done right, your attire should quietly say, “I took the invitation seriously — but I made it my own.”

6. Black Tie Optional Dress Code For Women and Men – Quick Summary

For those who want the essentials at a glance, this section breaks down the black tie optional dress code into key points and practical tips for both women and men. Think of it as your go-to reference for dressing elegantly while staying comfortable and confident.

Black Tie Optional Dress Code – Key Points

• Formality Level: Black tie optional sits between traditional black tie and formal business attire. It allows flexibility while maintaining an evening-appropriate level of elegance.
• Purpose: The dress code is designed to respect the formal nature of the event without pressuring guests into expensive tuxedos or evening gowns.
• Flexibility: Guests may choose full black tie attire (tuxedos or floor-length gowns) or a polished alternative (dark suit for men, cocktail or midi dress for women).
• Colors: Stick to darker tones like black, navy, charcoal, and jewel colors (emerald, burgundy) for evening events. Light or overly bright colors should be avoided for evening weddings.
• Accessories: Statement pieces can elevate a look, but subtlety is key. Cufflinks, pocket squares, and fine jewelry add refinement without overpowering the outfit.
• Footwear: Shoes must always be formal. Black patent leather or well-polished Oxfords for men; heels, elegant flats, or dressy sandals for women. Avoid casual footwear.
• Seasonal Adjustments: Lighter fabrics and shorter lengths are acceptable for daytime or summer weddings, while rich fabrics like velvet, silk, and satin are preferred for evening or winter events.

Men:

• Tuxedo Option: Classic black tuxedo with satin or grosgrain lapels, crisp white dress shirt, black bow tie, and polished leather shoes.
• Suit Alternative: Dark-colored suit (navy, charcoal, or black) with a white dress shirt, silk tie, and elegant accessories.
• Accessories: Pocket square, cufflinks, and a subtle watch.
• Footwear: Black leather Oxfords, wholecuts, or patent shoes; velvet loafers acceptable for more fashion-forward looks.

Tips: Ensure impeccable tailoring and grooming. A well-fitted suit or tuxedo is more important than following trends. Personalize subtly with textured fabrics or refined details.

Women:

• Floor-Length Gown: Preferred for most black tie optional events; conveys elegance and sophistication.
• Cocktail or Midi Dress: Acceptable alternative, particularly for younger guests or daytime events. Avoid anything above the knee for evening weddings.
• Jumpsuits or Pantsuits: Modern and stylish, suitable when structured and made from luxe fabrics. Avoid overly casual prints or fabrics.
• Colors and Fabrics: Stick to black, navy, jewel tones, or rich floral prints; silk, satin, chiffon, and velvet elevate the look.
• Accessories: Statement clutch, evening bag, elegant jewelry (diamonds, pearls, or subtle statement pieces).
• Footwear: Heels, embellished flats, or stylish lace-up shoes; avoid casual sandals or wedges.

Tip: Comfort matters — airy fabrics for summer weddings, structured silhouettes for winter or evening events. Accessories can balance a shorter hemline or modern cut.

Both:

• Avoid Casual Attire: Jeans, T-shirts, sneakers, sandals, or sun dresses are not acceptable.
• Respect the Event: While flexible, the dress code remains formal. Slightly overdressing is always better than underdressing.
• Consistency: Guests should aim for a level of formality comparable to the wedding party. Black tie optional allows personal flair but does not excuse casual mistakes.
• Key Philosophy: Think elegant versatility — you have room to show personal style while honoring the sophistication of the event.
