Well I would say to go to the mall like 3 weeks or even a month befor prom and get your dress cheaper. Because when prom kicks in they boost the cost and it will cost you more.

My prom dress is going to be a beautiful pink strapless dress with little pink flowers on it, it is also floor length. I don`t prefer a short prom dress. They look tacky to me. Not all of them look tacky but I think alot do! If I were you I would get the most beautiful dress you can find that YOU like the most! I would try to find one that's cheap because you can find a great prom dress that doesn`t cost very much. I got my dress for only $37.55. (it was on sale).
