This is an exciting time to create lifelong memories, take great photos, and of course, dress up. Sometimes, a special night like prom can also be a little stressful once you add up the costs. Your prom ticket, transportation, outfit, shoes, hair and makeup, and corsage, are just some of those purchases that can really add up to quite a pretty penny.
