you should definetely try modcloth! they have amazing vintage and indie styled clothes..well the indie clothing won't help lol but the vintage clothing kinda will. well, anyway you should check that store out online or just at the mall or something. i think they would have a dress similar to what you are looking for
Hope this helped :)
