I bought this three years ago. I've worn it about five times. It's sheer, and it originally came with a camisole, but I didn't use the camisole and threw it away. Therefore, please note that I am only selling the blouse, not the set. The size is M. I am 157cm tall with a standard build, and it was a little loose on me. It can be worn both elegantly and casually, and I think it will be useful in the coming season.
