I'm 5'6", 130-135 lbs, 32B bra, 27" waist, 36" hips. I ordered the medium, based on reviews. I bought these bras because I had been wanting to try the bandeau style, and because I wanted to wear an off the shoulder shirt for Easter. When I first tried them on, they seemed to fit okay, I suppose... but when I actually wore one of them as a bra on Easter, the whole thing kept falling down around my waist (granted, I was running to church). It almost ended up being a major wardrobe malfunction. I had to keep pulling my bra up. When I got home, I put on a real strapless bra with padding, underwire, the whole thing. I wore one of the bandeau bralettes over it, and while my regular bra stayed up, the bandeau kept falling down, and ended up being a waste of time. I'm incredibly disappointed. I'll probably try to sew the seams in so that it's smaller and fits better, because if I bought this, I want to get my money's worth.
