This is a JIV jacket, purchased at Jingu. It's made of a thin, flowy fabric. It's lightweight, highly stretchy, and an excellent piece that protects the body. I wore it for about six months. The collar and sleeves are noticeably dirty, so I hope someone who doesn't mind can wear it. Size (measured flat): Length: 42cm Width: 32cm Sleeve Length: 47cm I forgot the size notation at the time of purchase, but I think it would fit heights from around 120cm to 135cm.
