This is a Muji brand 100% cotton white shirt. Although it's white, the fabric is relatively sturdy, so it's mostly not see-through. I only wore it once over a T-shirt and have washed it at home. The size is M. I've measured it while laying it flat on a table, so please use these measurements as a reference: Shoulder width: Approximately 50cm Body width: Approximately 60cm Length: Approximately 77cm Sleeve length: Approximately 52cm Color: White系 (White-based) Material: Cotton
