Hey! We do have a few prom dresses, http://modcloth.com/store/ModCloth/Womens/Dresses/Party?pp=All «. But not a lot of them are in larger sizes than a large, there are a few though! But to be honest girl, I would just google “plus-size” prom dresses you should probably find some good stuff there!! :) Good luck! And Happy PROM! :D
