This item was purchased about 10 years ago. I've worn it a few times. There are no stains or damage. The size is M, which is probably equivalent to L in Japan. It has the exact same fit as an old Ralph Lauren shirt. Shoulder width is 45cm, sleeve length is 62cm, chest (underarm to underarm) is 55cm, waist is 55cm, and length is 77cm. This is a garage sale by an amateur, so please refrain from making claims or returns.
