Navy short-sleeved T-shirt from POLO RALPH LAUREN. It is labeled as size XS, but I wore the same size XS that I bought at the same time when I was a Japanese size M. I purchased this item as a spare because I liked this product, but I am selling it because I outgrew it without using it. * As shown in photo 6, the back of the tag print is slightly darker. Personally, I don't think it's something to worry about. Although it is new, please consider purchasing if you understand that it has been stored at home.
