What type of prom dress should a short girl wear?

Wear a long dress, preferably fitted. More sleek and sophisticated dress will make you seem it! A block colour or a non printed dress would probably be best. However a short dress with a full skirt is also fine for short girls (don't wear a long full skirted one though). Whatever you do don't go for anything between over the knee to ankle. Long ruffles add the illusion of height.

Make sure you wear heels. Big heels! You don't want to be too small in your photos!
