What dress is Taylor Swift wearing in Speak Now?

I like the dress, too. I love Taylor! As to where to buy the dress, I'm not sure, but in Entertainment Magazine, there is an article where if you seen something you like that a celeb wears, you can e-mail them, and they'll try to find it for you. Not sure if you read the magazine or not. I tried to find it on their website, but no luck. I have a subscription to the magazine, and every now and again they have a section where people write in and ask where a celeb got a certain outfit or jewelry from a show, movie or music video. Flip through the magazine or their website. Hope that helps!
