Cotton Japanese street wear sweatshirt, Sz M

Got this sweatshirt in Tokyo a few years ago for my teen daughter, but was told it a unisex item by the store. Super soft and stretchy cotton fabric in a grey color with a purple hue. Size tag was removed but it fits like a size Med, about 18.5” pit to pit and about 23” long, will fit a Small if you like it to have a loose fit, or a Large if you prefer it fitted and closer to the body. The only flaw is shown on a last pic - a tiny spot on the bottom front which I’m sure will come off in a wash. Blk02
