This item came out of a drawer, unworn and still in its plastic bag. It's made in Japan by the manufacturer Rose Color. I opened it for the photos. I will air it out lightly before sending it. It's 100% cotton gauze. The yarn is thicker than usual gauze, and the weave is tighter, giving it a feel similar to bleached cotton. It absorbs sweat well, so it's essential for wearing under a yukata or in summer. The sleeves are made of wrinkle-resistant synthetic fiber, and feature a light-colored floral design that won't show through. The size is M. The specific measurements are noted on the attached paper, so please check the photos. I will fold it up small and send it via Nekopos. Please be aware that it may get slightly wrinkled.
