Thank you for viewing! I purchased this previously at the Ginza store. I've worn it a few times. There are no noticeable scratches. It's an easy-to-wear design and feels good against the skin. It's 100% cotton. It's a thin sweatshirt material. The size is listed as "muscle," which I don't understand. Shoulder width: 44cm Chest: 50cm Length: 73cm Measurements are taken with the item laid flat, and are approximate. Please allow for some margin of error. Color: Gray
