What is your prom makeup style? Find out and look your best for prom! 1. I'm still shopping for my prom dress, but the one I'm going to buy is definitely going to be: Incredibly sophisticated. It's a long gown, but the front plunges into a deep V neckline. Long, wispy and flowing. I want a dress that has a gauzy feel to it. Avant garde. I really want to make a statement. Short! A long gown is more apt to get in my way while I'm dancing. Long, but classically cut. The gown I love is done in the mermaid style, and has delicate straps that show off my toned arms.
