This is a Y's lace sweatshirt. The body is made of lace, and the sleeves are made of sweatshirt material. The width is not too wide, so I think adults can wear it beautifully. The material is 85% cotton and 15% lyocell for the sweatshirt, and 84% nylon and 16% cotton for the lace. I have only worn it a few times, so it is in beautiful condition.
