My hip measurement is a size larger than my waist measurement, I ordered according to my hip size on the size chart just in case. The material is quite stretchy and I could have ordered the smaller size because they are looser around the waist and knee. I find them comfortable, but did notice some of the stitching is a little off. I like the deep color and am wearing them for the first time today. Other than having to pull them up occasionally, I like them well enough. Not sure of the long term durability though because of the stretchy fabric.
