This is a sample product. 【Product Description】 There is no material tag, but I believe it is cotton with a few percent polyurethane. It looks like a T-shirt material, and the upper part (image 2) is blouse-like. It has stretch and is easy to wear. The neckline has four buttons. When I checked the buttons, there were three small spots of discoloration near the second button (see image 9). Since it's in a hidden area, it's not noticeable from the outside. *Please read the profile before purchasing♪
