I bought this in two sizes: Small and an XS and none of them fit. I'm 5'4 and 120lbs. They seem to have been made for huge chests and giant behinds and the XS was even bigger on the chest than the small and same size as the small around the hips but just shorter. Very confusing sizing and fit and on both the straps were way too loose. On top of that they were faulty and came with stains on them and seams coming out but well I wrote customer service and they sent me a voucher to get something else. Would have rather gotten my money back though. All in all I wish they fit because they look cute on the picture but there was nothing I could do. If you are of slimmer stature with a small chest. this won't fit you at all. I would even say that if you are of regular build it won't fit either, only maybe an ultra curvy person.
