I wore this once and have washed it at home. The size is 0. There are three buttons to adjust the length of the waist belt. Shortest: Approximately 66cm, Longest: Approximately 70cm *There may be some error due to personal measurement. It has a lining, so I didn't have to worry about it sticking to my legs or being see-through. There are pockets on both sides. (The back pockets are fake.) There may be some creases when packing. Please purchase only if you understand this.
