Have you tried here? I know they aren't "real" but I have heard the quality is good and they look like the real thing. Can't hardly go wrong for the price either!!

I think the Louis Vuitton bags, the Juicy ones, and the Coach ones are really cute! Most are shipped from overseas so you have to do some research and pick a buyer with reasonable shipping plus good feedback but I think they are cute.
