I loved this on the mannequin and assumed it would look terrible on me. i tried it on anyway and was delightfully surprised. i tried a small and it was too roomy in the top so i opted for the extra small. i'm 5'6" and 130 lbs, (27 in jeans, 34a). my booty definitely fills it out but the rest of the fit is similar to the model. it is hard to get on and off but if you tie a looser bow before slipping it over your head it's much easier to get back on and you can tighten it up again fairly easily. f
