With such a downright fabulous dress, it's no wonder that two celebrities have already been all over it. Mandy Moore was a Fab favorite in her asymmetrical Preen LBD when she wore it in October. She looked classy with a hint of sultry. Her accessories included a silver clutch and black pumps. Cindy Crawford wore the same dress while out on the town in London this week. Someone had a good time! She wore pointier black pumps and opted for a sparkly black clutch. There's no denying that both ladies look smokin', but who wore it better?
