This is a three-piece set: top and bottom innerwear, and tabi socks. I purchased this set and used it for a wedding. It is men's innerwear for Japanese traditional clothing. There are no noticeable stains, but it has been stored by a private individual. Top and Bottom: M size Tabi socks: 27.0cm I usually wear a size S, but this fit me well.
