Knit Blend, elastic waist. Generous sizing on top, can be worn as tank, vest or shell. Elastic waist with white trim at bottom. I’m throwing in the Obey no.1989 lip & hearts graphic print off white or creme rayon shirt. Moving again soon, real closet clearing. As a life long collector of vintage & other clothing, that doesn’t ensure the closet will be cleaned out. This is a great buy.
