I used this when my child attended Oasis Kids for a short period. I withdrew after 1-2 months, so it was worn about 4-8 times. There are some small pills on the abdomen and the seat area from use. The size is S. I'm not sure about the general size, but according to other sellers, it seems like around 140cm is the目安 (guide), so I've categorized it as 140. I cannot be held responsible for the size, so please research before purchasing. Thank you for your understanding.
