This is a GUY ROVER shirt. It's made of thick, 100% cotton with a vintage feel, and is a gray size M (I believe it's a Japanese size L). It's a shirt with a denim-like texture. It has been worn (although I don't think there are any particularly large scratches or stains, I'm listing it as such), but I think it's still perfectly wearable. Measurements are: length 72cm, shoulder width 42cm, chest width 54cm, sleeve length 63cm. It was too small for me, so I rarely wore it. Thank you.
