Thank you for viewing. I purchased this in size OT, but it was slimmer than expected, so I've only worn it once. The flat-lay, amateur measurement is 53cm for the width. It can be worn by older elementary school children. There are no names written on the tags. It has been stored, but the tag is slightly yellowed. If you don't mind, how about it? It's in relatively good condition, but I cannot accept returns even if there are any oversights. Shoulder width / Body width / Sleeve length / Length Body width...53cm Color...Navy系 (Navy-based)
