These leggings fit nice and look great. I like the smooth fabric that is used for butt and legs . Great for warmer weather. The waist is a ribbed stretch fabric that fits smooth and doesn't dig in.
I have very slim thighs and legs and the fabric still clings nicely. I am a size small in all clothing and other brands of athletic wear. However I wear a large in Amelia as I find the styles are cut very small and tight with lots of compression. The large size still clings and fits smooth to my small body. For reference I am 5ft 2" tall. 108 lbs, 27 waist, 36 hip. BMI is 19.5
