Ashley Greene is the spokesperson for DonateMyDress.org.
Donate My Dress encourages girls to donate their Prom and special occasion dresses to those in need. It is the first national network to bring together local dress drive organizations across the U.S.. They help you find one in your area so that once you've had your dream night, you can give another girl hers!
Ashley will be doing a live twitterview today at 4:30pm EST. She will be answering all of your prom related questions. All you have to do is tweet to @donatemydress to submit your questions.
