Bella Swan Inspired Prom Dress. Many girls woul love to have a Bella Swan Inspired Prom Dress for the big dance and now you can get one. A company called Black Diamond Bridal in Washington is selling replicas of the dress worn by Kristen as Bella in the movie Twilight. Which I'm excited to say can't wait to see New Moon next month. Anyway the dress retails for only $139 which is a pretty good price for a prom dress. Created by shop owner Belva Bordey "wanted to give people the opportunity to dress in something festive which Bella wore". I like the idea that this company has some Bella inspired prom dresses, and you can also create your own by wearing a blue halter style gown on prom night. Either way Bella looked amazing and if you're trying to replicate her look for prom I'm sure you'll look gorgeous.
