This is an OAMC gray check overshirt. The size is S, but it's quite oversized, and I think it looks good worn with the shoulders slightly dropped. It's made of a durable, firm fabric, so it can be worn as an outer layer on its own, and it can also be worn as an inner layer under a coat in the coming season. Shoulder width: 54cm Body width: 79cm Length: 85cm Sleeve length: 62cm Thank you.
