This is a long-sleeved GU checkered shirt. The size is M. I wore it 5 times and stored it in a drawer. I'm selling it because I don't use it anymore. There are no noticeable stains, but it shows signs of wear. It's thin, so you can wear it as an inner layer, or use it as a light jacket on slightly chilly days. It's made of a soft material, so it's comfortable to wear! Please refrain from purchasing if you are sensitive to used items or do not understand that this is a used item.
