This is a Lacoste polo shirt. The size is indicated as 2 (The size feeling is borrowed from the Lacoste official website, photo 7) According to the official website, size 2 is XS size, but I usually wear size S and sometimes size M depending on the item, and this fit me perfectly, so I am listing it as size S. It has been worn several times, so there is a feeling of use, but I think you can still wear it. I will pack it compactly when shipping. Please feel free to comment if you have any questions.
