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 a rare opportunity to don your very best attire can actually be pretty fun. Who doesn't want to feel like royalty for a night in a floor-sweeping evening gown or dapper tuxedo? We encourage you to go all out in your finest formal wear for black-tie functions. (There's actually only one wedding dress code that's a step above black tie in formality, and that's white-tie attire.)

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.

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 Demystified

Now that you know what black-tie attire is, how does the dress code differ between men and women? Here's what you're expected to wear for upscale functions, as well as suggestions for shoes, accessories and more.

Black-Tie Attire for Women

If you plan on wearing a black-tie wedding guest dress (or a tux or jumpsuit), it's recommended that you pair your outfit with accessories to elevate the look even further. For shoes, options include heels, peep-toe stilettos, heeled sandals, dressy flats and loafers, depending on your preference. As for your accessories, you can't go wrong with sparkly jewelry (think: drop earrings, a statement neckline or a crystal bracelet) and an embellished clutch.

Black-Tie Wedding Attire for Men

For men, a black-tie wedding doesn't just mean renting a tux—guests should pair it with a plain tuxedo shirt and accessories, including a bow tie, a polished pair of dress shoes (appropriate tux shoes include patent leather loafers, dark derby shoes or velvet loafers) and an optional cummerbund to complete their outfit.

Your Black-Tie Attire Questions Answered

Still have questions about what a black-tie wedding really 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.

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

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 suit to a black-tie 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 own outfits. That said, suits aren't completely out of the question. "Men can wear a tux, but are also fine to wear a nice black, gray or navy suit," says Mayer. If you're wearing a suit, you should plan to keep it minimal; choose a dark color and wear a bow tie.

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.

Can you wear black to a black-tie wedding?

It's 100% acceptable to wear black to a black-tie wedding (and in a lot of cases, it's actually preferred for men to wear a classic black tuxedo). Darker colors are considered more formal, making them completely appropriate for a black-tie event.
