This is a rare pair of NIKE overalls, not sold in Japan. US size XS (in my opinion, equivalent to Japanese sizes S to M). The length is adjustable with the shoulder straps, so you can wear it to fit your height to some extent. I am 174cm tall and weigh 60kg, and I wore it with a slightly tight fit. This is a popular discontinued model, worn by Yoshi from Metron Blog. Overall, it is in a clean condition with no noticeable scratches or stains, but as shown in photos 6 and 7, there is a small tear on the back of the right thigh. I have repaired it with nylon repair tape from the surface and the back of the fabric so that it is not noticeable, and I personally didn't mind wearing it. I will also include the nylon repair tape when shipping. This is a used item, so please refrain from purchasing if you are concerned. Non-smoking, no pets.
