Kids' size 160, but I think it can be worn by someone who usually wears a slim XS! I'm selling it because my child outgrew it in one season. ● Size: 160 ● Color: Black ● Condition: There are no noticeable frays or stains. ● Tag: No name written ● Waist: Elastic + drawstring ● Other notes: Stored at home. Please check the photos for details of the design. Please understand that this is a used item worn by a child before purchasing.
