I bought 2 sizes up (based on PACT website chart not Amazon) and one size up from my normal size yoga pant. After washing/drying low, it fits with maybe 1/2-1" to spare in waist. The material is thicker cotton than most leggings which means it isn't see through. The waist band is thicker so it does not cut into my fat. These are nicer than $100 leggings. Plus, they are certified fair trade not slave labor like other yoga brands tend to use.

I am 5'6, currently 25" waist, 34" hips with a slightly long torso and legs. Medium says for 40-42" hip, so they are waaaay off since it is snug on me. It comes mid waist on me (below the model). There is maybe 1 inch to spare on leg length. The thighs are snug on my 22" but less than other brands which is great. These are comfortable.
