This is a cotton inner shirt purchased from UNIQLO in 2024. I am selling it because it no longer fits. I wore it about twice a week, as I had eight shirts to rotate through. Last year, it didn't get cold until later in the season, so I only wore it for about four months. There is a little bit of adhesive residue left on the product tag from a name sticker. I apologize for that. Otherwise, I don't think there are any stains, but please refrain from purchasing if you are concerned. m(_ _)m
