Since our leggings are made of the lightweight and stretchy Zensoft fabric, sizes are not as "size sensitive" as a pair of jeans for example. Order your normal size, but if you are between two sizes, we recommend that you choose the smaller size. If you need additional information, please refer to our size chart for general measurements. If you still have any other questions, please do not hesitate to email us at support@zencoreyoga.com.
