Simple white three-quarter sleeve T-shirt with a round neck design. It has stretch and feels good against the skin, so it seems like it would be useful as an inner layer. Although the paper tag is not attached, it has been stored with only the plastic string remaining. The size is unknown, but I think it feels like a size S~M. Please check the following flat measurements for reference.
