Don’t stress. We’ve created the definitive guide to decode every wedding dress code imaginable. From the most opulent galas to breezy beachside ceremonies, you’ll know exactly what to wear to arrive in style and confidence.

The Ultimate Guide to Wedding Guest Dress Code for Every Wedding Styles

The Most Formal: White-Tie

This is the absolute peak of formality, reserved for ultra-luxe events like royal weddings or state dinners. It’s rare, so if you see it, the couple is planning a truly magnificent affair.

• For Women: A formal, floor-length evening gown is required. No exceptions. Pair it with your best jewelry, elegant heels, and a sophisticated clutch.
• For Men: A black tuxedo with tails is mandatory. This is paired with a white piqué wing-collared shirt, a white vest, a white bow tie, white or gray gloves, and formal black patent leather shoes (like oxfords or derby shoes).

The Classic Formal: Black-Tie

A step down from White-Tie but still highly formal, Black-Tie indicates a glamorous evening event.

• For Women: A floor-length gown is the preferred choice. You can also opt for a very sophisticated, ankle-length dress or a chic, formal pantsuit in a luxurious fabric like silk or satin.
• For Men: A classic tuxedo is a must. It should be worn with a black bow tie, a black vest or cummerbund, and black patent leather shoes. For warm-weather or summer events, a white dinner jacket with black tuxedo trousers is a stylish and acceptable alternative.

The Flexible Formal: Formal or Black-Tie Optional

This code offers a bit more flexibility, especially for men. It signals a formal event, but with options.

• For Women: The guidelines are very similar to Black-Tie. A floor-length gown, a fancy cocktail dress (think ankle-length or a very dressy midi), or an elegant pantsuit are all appropriate choices.
• For Men: A tuxedo is welcome, but not required. A formal dark suit (in black, charcoal, or navy) with a crisp white shirt and a conservative tie is a perfectly polished alternative.

The Wedding Go-To: Cocktail Attire

This is one of the most common dress codes. It strikes the perfect balance between elegant and comfortable, and formal and relaxed.

• For Women: It’s time for shorter hemlines. Opt for a tea-length, knee-length, or midi dress. A chic jumpsuit or a dressy separates look (like a silk skirt and top) also works beautifully.
• For Men: Tuxedos are out. A suit and tie are required. The color of the suit can vary depending on the season and time of day.

The Ambiguous Middle Ground: Semi-Formal or Dressy Casual

This code can be tricky, as it often depends on the time of day. Use the event’s timing as your guide.

• For Daytime Events: Think light colors and airy fabrics.
• For Evening Events: Lean into darker, more formal hues.
• For Women: A below-the-knee dress, a stylish slip dress, a dressy skirt and top, or an elegant pantsuit are great options. Heels, wedges, or formal flats complete the look.
• For Men: A dress shirt and slacks are the standard. A tie is optional but recommended. A sport coat or blazer can elevate the look.

The Fun & Fashionable: Festive Attire

Relatively new to the scene, this dress code invites you to have fun with your outfit. Think Cocktail attire with a personality boost.

• For Women: Choose a cocktail-style dress with bolder colors, playful prints, and fun accessories. This is your chance to show off your personal style.
• For Men: Sport a suit in a more interesting color, pattern, or texture. Liven it up with a bright tie, a unique pocket square, or novelty socks.

The Relaxed Celebration: Casual Attire

“Casual” for a wedding is a world away from your everyday weekend wear. It usually suggests an outdoor or beach setting with a laid-back vibe.

What NOT to Wear:

Unless specifically stated by the couple, avoid jeans, shorts, t-shirts, tank tops, and sneakers.

What to Wear:

• For Women: A summer sundress, a floral midi or mini dress, or a nice jumpsuit is perfect. Pair with wedges or dressy sandals.
• For Men: Dress pants or khakis with a collared shirt are a safe bet. You can add a sport coat or a tie, but they’re generally not required.

The Getaway Vibe: Tropical or Destination Attire

This code calls for outfits that can handle heat and humidity while still looking elegant. Think lightweight, breathable fabrics.

• For Women: Look for tropical-print dresses in cotton or linen. Nice sandals or wedges are essential for sand or uneven ground. A stylish sunhat is a great accessory for an outdoor ceremony.
• For Men: A Guayabera shirt (also known as a “Mexican wedding shirt”) is a fantastic choice. Linen shirts and pants are also appropriate. Pro Tip: Linen wrinkles easily, so if you’re traveling, consider packing a portable steamer.

The Unique Vision: Concept or Themed Attire

This is straightforward: the couple has a specific aesthetic in mind and wants you to be a part of it. The theme will be stated on the invitation, such as “All-White Formal,” “Roaring ’20s Gatsby,” or “Bohemian Chic.” Your job is to find inspiration and have fun dressing the part!

The Ultimate Trust Fall: Come As You Are

While it sounds freeing, this can be the most confusing code of all. It means the couple wants you to feel comfortable. To avoid feeling over or underdressed, use context clues. Consider the venue, the time of day, and the season to guide your choice. When in doubt, aim for a Dressy Casual or Cocktail look.

What if the invitation has NO dress code?

If neither the wedding invitation nor the couple has specified a dress code, use context clues, such as the tone of the wedding invitation, the venue, the time of day, the season, and the religion (if applicable) of the ceremony, to decide what to wear. When in doubt, a knee-length cocktail dress for a woman and a dark suit for a man will usually suffice.

What should I absolutely NOT wear to a wedding?

• White: Avoid any shade of white, ivory, or cream unless the dress code specifically requests it (e.g., an all-white party). Let the bride have her moment.
• The Bridal Party’s Colors: If you know the colors the bridesmaids or groomsmen are wearing, try to choose a different hue.
• Anything Overly Revealing or Flashy: A wedding is a celebratory but respectful event. Keep outfits tasteful and avoid anything that might pull focus.
• Denim or Sneakers: Even for a “Casual” wedding, these items are almost always a no-go. Elevate your look to show respect for the occasion.
