20 Sexy Prom Dresses That'll Instantly Boost Your Confidence For The Big Dance

Prom is one of the few chances that most girls have in their life to get really, really dressed up. Most of us aren't going to land on a red carpet in our lifetime, so there's really just your wedding, maybe a few fancy black-tie events if you're lucky, and prom. Most people go the classy white dress route for their wedding, and most black-tie affairs are work-related, for charity, or otherwise unsuitable for a bedazzled thigh-high slit. A truly sexy prom dress is one that makes you feel confident and gorgeous — both on the dance floor, and when you look back at photos from the big night.

Click through for 20 dresses basically guaranteed to make you feel your best at prom.

A Sexy Statement

OK, so this first one isn’t actually a dress. If you want to stand out at your prom, consider a romper or jumpsuit. Breaking away from the norm is always hot.

Sexy Boho Style

You can stay true to your bohemian style and still look glam in this dress.
