This is a tank top by JANE SMITH. I bought it this year. I've worn it about twice. There's nothing particularly noteworthy about it, and it's still in good condition. The following is a product description: A tank top with a unique design featuring shoulder straps at the top and bottom. The shoulder straps of the tank top can be removed with dot buttons, and a tank top with different shoulder strap widths is attached to the hem, upside down. You can wear it with only one side detached, or layer it like a bra top. Material: 100% cotton Size: 38 Total length 66.5cm, Shoulder width 26cm, Body width 36.5cm Retail price: ¥17,600
