I bought this new last fall, tried it on once indoors, and was going to have my child wear it in the winter, but they outgrew it, so I'm selling it. It hasn't been worn outside, so there's no mud or dirt. The size is M. Please refer to the size chart in the 9th and 10th photos. The color looks pink in the photos, but the color in the 7th and 8th photos is the closest. I apologize that I couldn't take better pictures. Since it was worn once, there might be some dog hair on it. Please purchase if you don't mind. I bought it for around 3100 yen. The white line in the first photo is a gray reflective line.
