Finding the perfect black tie wedding guest dress can feel like a high-stakes assignment — but it’s also one of the best excuses to dress up you’ll ever get. As you might’ve noticed, wedding dress codes have become a lot more popular, with couples moving toward more formal celebrations, like this Carmel Valley Ranch wedding, this art museum wedding, or this desert wedding. Whether your invite says “black tie” or “black tie optional,” we’ve rounded up 40+ dresses — from floor-length gowns to formal cocktail dresses — so you can show up looking absolutely stunning.

In our guide to dressing for black tie occasions, you’ll find a little something for everyone: ball gowns, floor length gowns, elevated cocktail dresses, elegant suits, and some statement shoes and accessories too, and the right time to opt for each. Shall we?

When it comes to shopping for black tie wedding guest dresses, a few retailers consistently deliver on the elevated, occasion-ready styles you need. Our favorites for formal wedding guest dressing:

• Revolve — fashion-forward floor-length gowns and elevated cocktail styles perfect for black tie
• Anthropologie — romantic, unique options that lean feminine and floral, great for garden or estate black tie weddings
• Nordstrom — wide range of price points with reliable sizing and same-day shipping options
• Shopbop — designer and contemporary picks with a strong selection of sleek, minimalist formal styles
• Reformation — sustainably made, figure-flattering gowns with a cool-girl edge
• Tuckernuck – is a go-to for polished, feminine wedding guest dresses that feel classic but still current.

What does “Black Tie Optional” mean, exactly?

If your invitation reads “black tie optional,” black tie dress is highly encouraged, but you have a little flexibility with how formal you’d like to get. You’re being invited to an event at an elevated venue, with food, drink, and décor that sets the tone for black tie attire. A ball gown wouldn’t look out of place here, so if you’ve been vying for the chance to give one a whirl, now is the time. It also means that many guests will be in black tie attire. People love the chance to dress up, and nobody wants to look underdressed at a wedding or special event, so you can expect plenty of guests to don floor length dresses and tuxedos.

That said, black tie optional dress codes give you more freedom than the invite that drops the “optional” bit. The hosts are inviting you to dress up, but you can choose whether to opt for slightly more relaxed formalwear like cocktail dresses and suits or go all-out with black tie.

Black Tie Optional for Men

Black tie optional dress for men means that you can wear a suit instead of a tuxedo, but you should consider how it will fit in with all of the other black tie dress at the event. A dark suit is recommended, but guys also get creative with the tie or bowtie, pocket square, and undershirt as well as textures within the suit itself.

Elegant Dress Ideas

Women will likely be in floor length dresses at a black tie optional wedding or event, but you can expect guests in formal cocktail dresses (think chic dinner party, not party dress) too. Accessories, jewelry, hair, makeup and shoes all contribute to your final look, so if you fall in love with a cocktail dress rather than a gown, you can always dress it up!

Consider the Season, Style, and Venue

As with any wedding, there are other considerations to make when dressing for the event. Consider the season, especially if the couple are tailoring their wedding theme and palette to it, such as a garden wedding in the springtime or an indoor affair in winter. Invitations tell a lot about the wedding style, as do the events leading up to it, so take cues from information the couple has already shared. Black tie attire can fit into an event in any season, but this can guide you to colors and styles that fit the vibe! Lastly, look to the venue for inspiration for your outfit; from a historic estate to a farm to a country club, there are many ways to match your dress to the ambiance.
