I will ship this item via Rakuraku Mercari Bin or Yuyu Mercari Bin, which offer anonymous shipping. It's a bit difficult to see, but the material is a smooth polyester. The sleeves have no lining and are sheer, allowing a slight see-through effect. Lining: The lining is detached at the side zipper (see photo 4). Apart from the damage to the lining, the item is in good condition. No material label, but I believe it's polyester. 【Size】 Free Size Width: 49cm Shoulder Width: 37.5cm Waist: 40cm Length: 116cm Please excuse any slight discrepancies, as I am not a professional seller. m(__)m
