What dress is better?

I can,t choose between these two dresses, choose on, and what ever dress gets the most likes is the one i'm going to get. http://www.modcloth.com/Womens/Dresses/-Betsey-Johnson-Belle-of-the-Barre-Dress or http://www.newyorkdress.com/Party_Time/6381PT.html (this is for my 8th grade grad) Thanks.
