This item was included in a 2021 lucky bag. The tag has been removed, but it's in beautiful condition, only tried on at home. The size is L, as indicated below, but I'm listing it as M because I think it would be perfect for a child who wears size 170. Chest: 96-104 Height: 175-185 The following are approximate measurements, as I am measuring them myself: Shoulder width: 50cm Body width: 56cm Sleeve length: 63cm Length: 70cm Color: Black系 (Black-based) Stains, tears, odors, etc.: None
