How it works
Choose the color of the dress, or the main color your date is wearing. Then choose how closely you want to match. Matching puts the dress color on one accent, usually the tie or bow tie. Coordinating uses a color that sits well beside it without copying it. Classic keeps the accents black, white or silver and lets the dress stand alone.
The suggestions follow a simple rule common in formalwear styling. Keep the suit neutral, tie the outfits together with one accent, and let the flowers connect the two. Our page on matching a suit to a prom dress explains the thinking, and our guide to what guys wear to prom covers the rest of the outfit.
Get a swatch
Screens and photos never show color exactly, and the same color name can look very different from one designer to the next. Bring a real fabric swatch when you choose the tie, vest and flowers, since rental shops and florists can match fabric far better than a phone photo. Our guide to matching a suit to a dress lists the easiest ways to get one.
Not just for a date in a dress
The same approach works for any pair, whether one of you wears a suit, both of you do, or you are coordinating a whole group. Pick the color you want to coordinate with and use the suggestions as a starting point. If you are renting, reserve early, since rental companies ask for several weeks' notice. Many prom shops listed on this site also handle tuxedo and suit rentals.
