Purchased for ¥1999 on Mercari SHOP. I am selling this because I no longer need it for a concert. The description stated that it is made of a soft, stretchy material, and the boning on the sides is flexible, making it comfortable to wear. It has adjustable hooks (see photos). The size is L, but it is for: B80 size Underbust: 78-82cm Top bust: 90-92cm The bag is torn.
