This is a T-shirt by Yuma Asami. It shows signs of wear, with discoloration around the neckline, but it's still wearable. The size label is unreadable, so I'm listing it as a size M. Purchased at Beams. It's a product from about 15 years ago. Width: 51cm Sleeve Length: 20cm Length: 70cm cex work (front) the mask (back)
