I think it would be good as an undershirt or pajamas. I bought it about 10 years ago as a substitute for gym clothes before a sports day and wore it once or twice. There are some stains from the sand on the school grounds that didn't come out after washing, and some light stains (school...). Please consider this, understanding that it has been stored at home for a long time and has been inspected by an amateur! #tantan1911
