I'm selling this because the size is too small for me. I haven't worn it much. 99% cotton 1% polyurethane The fabric is sturdy. Shoulder width: 40cm Width (at the bust): 45cm The waist is slightly cinched, so it's 40cm there. Please consider this item if you understand that it is a used item. The price has already been reduced, so please refrain from negotiating the price.
