This is my first time trying these joggers. In most other brands, I wear mediums, but I sized up to a large for these leopards. I love these pants so freaking much. They're compressive, silky, and the waistband is actually nice and taut. I'm 5'7" and about 160lbs; thighs are 26" around each, butt/hips are 42" at the widest, and my waist is 27" (and these pants do hit at your true waist, right at the nelly button). I recommend these for people who enjoy the feel of endurance leggings and want a similar feel in their joggers.
