If you were invited to a wedding with a formal or black-tie optional dress code, you might be wondering what you're supposed to wear. The formal dress code can certainly feel confusing: it's not as casual or playful as your typical go-to cocktail dress, but it's also not as fancy as black-tie or white-tie attire.

“The biggest difference between a formal and informal dress is the length,” explains bridal stylist Kennedy Bingham. “Generally, a formal dress will be a longer length, as well as an elevated material. So instead of a spandex or polyester fabric, the same dress in a nice crepe or silk could add to the formality of a dress,” she said. For women, this means your formal attire could be floor-length gowns, sophisticated jumpsuits or pantsuits (a midi or tea-length dress can be appropriate in some cases) in an elegant fabric.

What to Look for in a Formal Wedding Guest Dress

  • Style: If you were invited to a wedding with formal attire, pull out all the stops and wear something fabulous. There's a time and a place for easy breezy cocktail dresses, but this isn't one of them. While “formal” can mean a lot of different things, in general, look for a long, glamorous dress in an elegant fabric. You can also take this as an opportunity to add extravagant jewelry. “The fun part is: the more formal, the more accessories! It's hard to go over the top with a super formal theme,” said Bingham.
  • Length: Longer hemlines are better for formal celebrations, so it's best to opt for a floor-length gown. “If you want to be safe rather than sorry, a chic, floor-length dress is always a good default,” said Bingham. While you can get away with a midi or tea-length number, be sure it's glamorous enough to fit the dress code. Additionally, a fancy jumpsuit would be lovely for those who are searching for something other than a dress. Skip out on anything with a short hemline, unless it’s been vetted or is on the fancier side.
  • Venue: If you’re unsure about the dress code for a particular wedding, a look at the venue can give you insight into what you should wear. For example, an outside, garden wedding might mean choosing an ankle- or tea-length gown, as well as dressing for the weather. A five-star hotel venue gives you the go-ahead for going super formal. But when in doubt, ask. “I've seen beautiful, formal backyard weddings and I've seen really gorgeous, casual weddings held in cathedrals. I would pick what feels the most true to your personal style,” said Bingham. In general, it’s better to err on the side of caution, and dress “up” instead of down.

FAQ

  • What does formal wedding guest attire mean?

    Formal wedding guest attire typically means long (or midi) gowns and tuxedos or suits. It’s a step up from cocktail attire, but not as fancy as black- or white-tie. According to Bingham, look for a dress in a long length with an elevated material (skip the jersey or spandex dresses). If you're feeling unsure of what to wear, always ask the couple or wedding party if your outfit is appropriate for the occasion.

  • Can you wear a cocktail dress for a formal dress code?

    Cocktail dresses are not completely off-limits, depending on the season and type of wedding. Make sure it leans towards the fancier side, though. Look for elevated cocktail pieces that are made of high-quality materials and fabrics. Neutrals or dark shades are always great too, but patterns and prints aren't out of the question.

  • Does formal attire always mean a long gown?

    Gowns are typically expected at a formal wedding. “When in doubt, go long. But obviously we see many people go to extremely formal events (Met Gala, red carpets, galas, etc.) in short gowns. The key is to make sure you aren't underdressing. There are short gowns that have a super interesting design, like Jourdan Dunn's Zac Posen gown for the Met Gala, that absolutely still feel formal even if they're short,” said Bingham. That said, you don't have to wear one to every formal event. Elegant maxi dresses can work with this dress code, and midi ensembles are an acceptable option too. Remember, though, the dress code ultimately depends on the overall vibe the couple has established for their wedding.
