Choose colors that match your skin tone.
Whether it is a formal prom or more casual will affect the type of dress you should wear. Keep this in mind.
Bring a friend or two along when you are trying on dresses. It is always better to get two or three opinions on such an important purchase.
On the other hand, you may want the dress to be a surprise. Or, your friends may have a completely different style to you. Instead take your mom with you or even your sister (if she is close to your age or older than you).
