I purchased this around autumn of last year at a used clothing store in Koenji. I'm not very knowledgeable, so I don't know the details, but I think it's a U.S. AIR FORCE lightweight jacket. The color is navy, and the length isn't long. It has ribbing at the hem, so it can be worn short, making it easy to use. I'm selling it because my style of clothing has changed. The actual color is closest to the color in the fifth photo. Length: 67cm Width: (Unspecified) Shoulder width: 49cm Sleeve length: 65cm
