What Is “Black Tie Optional”? The Most Confusing Wedding Dress Code, Explained

Essentially: the couple wants their wedding to look like and be a formal affair—but understands that implies fancier (and often more expensive) attire for guests. So they’re giving guests more aesthetic leeway to avoid any undue stress or burden to those who may not be able to wear a tuxedo or evening gown.

What Should I Wear to a Black Tie Wedding?

“I would try to wear floor-length dresses if possible,” Choi says. “If this is not an option, put in an effort and dress up your look with the right accessories. If your dress is on the shorter side, or if you opt for a jumpsuit or pants, make sure your shoes feel dressy–this doesn't necessarily mean heels; an embellished flat or a sharp lace-up oxfords could be appropriate options too.”

Emily Post Institute offers a similar definition: “A black-tie optional dress code gives guests a couple of formal options to choose from. Men are requested to wear a tuxedo, but can opt for a dark suit. Women can choose either a formal evening gown, a shorter cocktail dress, or dressy separates.”

What Shouldn’t I Wear to a Black Tie Wedding?

Make sure your dress, jumpsuit, or set comes in a formal fabric: “Cotton or linen sun dresses will look out of place and I would opt for silks, chiffons, or taffeta,” says Choi. In addition, stay away from casual footwear. “Just avoid day sandals, raffia wedges, and so on,” Choi says.
