This power net cut-and-sew is likely made of nylon, so 100% silk is valuable, I think. It can be hand-washed. The sleeves are unlined and have a see-through effect. I purchased it at Tsuruoka City Silk Kinumonogatari Shirahata. Size: M~L, Retail price: 14,850 yen. Chest width 44cm, shoulder width 39cm, sleeve length 50cm, length 55cm. There is a small tear in a part of the lining (photo 5).
