I purchased this last summer during a trip to Hida Takayama. It's thick. I wrote "commemorative" on it, but even a size S was too big for me. I think it would fit someone who usually wears a size S (on the larger side) or M. In the photo, it looks shiny under the armpits, but there is no discoloration at all. Thank you. (I selected "men's" but it's unisex.) Color: Red系 (Red-based) Stains/tears/smells: None
