There is no size notation, and I think it's a free size because it was one size when I bought it. Waist: 35cm The waist has elastic and a drawstring, so I think it's flexible. Length: 78cm All measurements are taken flat. Please note that there may be some errors due to amateur measurements. Please purchase after understanding that this is a used item checked by an amateur and stored at home. There may be changes between Yu-Yu Mercari delivery and Raku-Raku Mercari delivery.
