Koi fish boxy crop top

Extra large boxy koi fish shirt. 20in pit to pit, 19in long. Boxy fit crop top. The koi fish are like a felt how they feel. Bought brand new from Jcpenneys and only wore it once but got some stains on it. I’m not sure what the stains are, maybe benzoyl peroxide stains? Not sure but you can see in the pictures. The last three pictures are of the back.
