I really liked these leggings. They are flattering on, as they flatten the tum and don't show any muffin top because of the high waist. I am about 5'7" and size 10-12 (Aus). I got the small and it is perfect. I often find the legs are too short in leggings. The length is great. They are thicker than most leggings and warmer. I will be buying more.
