This is a top from the Setouchi High School jersey. The size is XO. It's quite large, with a loose fit for someone around 170cm tall. Shoulder width: approx. 63cm, Body width: approx. 65cm I bought two, and while I haven't worn this one much, it's not new, so please refrain from purchasing if you are sensitive to this. The name embroidery is still on it. Thank you.
