This Tatum waffle set is made out of polyester, Rayon, and spandex material. It’s a stretchy material that allows a soft and comfortable fit. The top is a light weight v-neck long sleeve that can be worn with the lounge pants or alone to make a cute simple outfit. On the jogger style pant there is a waist band that allows maximum stretch and comfort. There are three wooden mock buttons that add so much detail and style and then it is cuffed at the bottom to give you the jogger style.
