Thank you for viewing. This is a white button-down shirt from junhashimoto. I believe it cost nearly 30,000 yen. The material is cotton, with a slight thickness and firmness. The underarm side panels are switched to mesh material, contributing to a comfortable fit. Worn only 2 or 3 times. It has been dry cleaned. Size (approximate measurements): Shoulder width 41cm, Body width 46cm, Length 72cm, Sleeve length 64cm
