Model size: S, Activewear Sets include: 1 Piece Tank Top and 1 Piece Athletic Leggings. Material: 11% spandex, 89% polyester, the quality of this set is amazing! It looks like a more expensive gym set. The bra is great, and pants are really a homerun, very comfortable, fit Well. Particularly good for yoga, it will not roll down during yoga and other exercises. 5 energetic colors are available to choose, size from S to XL. The Asian size is smaller than US/Europe size, so we recommend you to buy the bigger size. The fabric is soft and comfortable, the color is exactly same to the photo. Even the top dresses very well, I would say that it is a good product for doing yoga. Totally worth buying!
