Please comment before purchasing. IB082 Selling price: ¥3,410 I'm selling this because the size doesn't fit me (;_;) The back is designed to be three-dimensional. The waist is folded over with the main fabric to reduce digging in. The leg openings are also folded over with the main fabric to reduce tightness. In addition, the leg opening length is 1-minute length, making it less likely to feel tight in the groin area.
