This is innerwear for dresses. I purchased it from Matsuya last year, tried it on only once, hand-washed it, and have been storing it. I'm selling it because the back is not very open. It fits very snugly, so there's a knack to putting it on. The size S is suitable for: Bust: 70-83 cm Waist: 58-64 cm Hips: 82-90 cm
