Receiving an invite to a black-tie wedding might send you into panic mode if you're unsure of what this dress code entails, but an opportunity to don your very best attire can be pretty fun. Who doesn't want to feel like royalty for a night in a floor-sweeping evening gown or dapper tuxedo? There's only one wedding dress code that's a step above black tie in formality, and that's white-tie attire. That said, we encourage you to go all out in your finest formal wear for black-tie functions.

Confused about what exactly a black-tie wedding dress code means? You've come to the right place. We're breaking down the etiquette with the help of Marteal Mayer, co-founder of sustainable Brooklyn bridal boutique Loulette Bride. But that's not all—we're also sharing some of our favorite black-tie wedding attire looks for men and women to help inspire your search for new formal wear.

In this article:


What Is Black-Tie Attire?

Typically, a black-tie wedding requires guests to wear either a tuxedo or an evening dress. "The lines have been blurred over the years, but it is safe to assume that black tie means fancy, and you really can't be too over-dressed, short of wearing a white, floor-length dress yourself," says Mayer. A tuxedo should be your first choice, but if you want to wear a suit instead, a black-tie event typically means wearing—you guessed it—a plain black necktie or bow tie. For those wearing a dress, a full-length evening gown is the norm. Guests are also expected to stick with darker colors, like navy and gray, and deeper jewel tones, like emerald, sapphire, or burgundy.

Black-Tie Dress Code Details & Variations

How does a black-tie dress code differ between men and women? We've got the answers. For upscale affairs and formal dress codes, here's everything you need to know–plus suggestions for shoes, accessories, and more.

Black-Tie Dress Code for Women

For women, black-tie dress codes mean a full-length dress (or a women's tuxedo, if you plan on suiting up–formal jumpsuits work, too). You should pair the dress with heels, dressy flats, or loafers. Short and mid-length dresses aren't going to be the best fit here.

Black-Tie Dress Code for Men

For guys, the black-tie dress code means it's time for a tuxedo. This means the full look–a proper dinner jacket, tuxedo pants, appropriate shoes, and the necessary accessories. No standard suits allowed, even the fanciest of them.

Black-Tie Preferred Dress Code

For a black-tie preferred dress code, guys are going to want to stick with a tux if it's possible. You can generally expect most suit-wearing guests to be wearing them, though if you need to, you can go with a suit. A suit in this case needs to be particularly formal, though–this means a dress shirt (maybe one with French cuffs), a tie, and perhaps a vest if you want to go with a three-piece look. For ladies, black-tie preferred still means a full-length dress, though there's a bit of flexibility–a nice cocktail dress will do in a cinch.

Black-Tie Optional Dress Code

Black-tie optional has a bit more wiggle room than black-tie preferred. Tuxes and floor-length dresses are probably the best move, but a formal suit (again, with a shirt and tie) or a cocktail dress will do just fine. Think of black-tie preferred as the dress code for which you should wear a tux or an evening dress and black-tie optional as the one for which you can wear a tux or an evening dress.

Your Black-Tie Attire Questions Answered

Still have questions about what a black-tie wedding means for your wardrobe? We've got you covered. Read on for our answers to some of the most frequently asked questions about black-tie wedding wear.

Does black-tie mean tuxedo?

For the suit-wearing type, yes, a black-tie dress code necessitates a tuxedo. There's wiggle room if the dress code is black-tie preferred or optional but if it's a black-tie wedding, you're expected to wear a tuxedo.

Does black-tie mean black dress?

No, a black-tie dress code doesn't refer to the color of your dress. You should go with a more subdued or evening-appropriate color, sure, but your evening dress at a black-tie wedding doesn't have to be black.

Can you wear a suit to a black-tie wedding?

If the dress code is black-tie without any modifiers, no, you shouldn't wear a suit to the wedding. Whether the dress code states "black-tie optional," "black-tie preferred," "black-tie invited" or just "black tie," you can assume that a tuxedo is your safest bet. The couple and their wedding party will be wearing their best black-tie attire on the big day, and it's respectful for guests to replicate that level of formality in their outfits.

Can you wear a short dress to a black-tie event?

As a black-tie wedding guest, you can't go wrong with a long formal gown (and if you don't get a lot of opportunities to wear one, you might want to go for it!). That said, it's not your only option, especially with a modern black-tie dress code. "For women, a floor-length dress is great, but a more fancy cocktail-length (midi dress) can also work," says Mayer. It's acceptable to wear a tea-length dress to a black-tie wedding, so long as it feels elevated enough and hits mid-calf or below. Opt for something with elegant embellishments (we're big fans of beading) and stick with darker hues.

Can You wear a jumpsuit to a black-tie wedding?

The short answer is yes! Jumpsuits have come a long way in the last few years, and according to Mayer, there are plenty of options out there that are suitable for a formal black-tie wedding. "Not all women want to wear dresses, nor do they have to," she says. Similar to cocktail dresses, make sure whatever style you choose feels elevated enough for an upscale event. We'd recommend avoiding styles with busy patterns or bright colors.
