I've worn this about 3 or 4 times, and it's in good condition. Regarding the size, I don't remember whether I ordered S or M, and I tried to check, but it's not written on the tag. When I checked the size laid flat, I think it's probably M. The back is elastic and stretches, so I think it can be worn with a free size feel! Actual size: Body width 40cm, Length 126cm, Waist 37cm
