Ok. So. I'm around an 18/22 depending on stretch and cut. I got the XX lg. I'm 5'1" with thick thighs and short sexy legs. I read the reviews that say go down a size. But I caution. If u have wide hips and narrow waist get ur size if u want a regular fit or go up one if u want a loose fit. Going down a size only seems like it works on women with slender/ average hips. These are straight leg and thus u must account for curves if u have them. Also. Being as that I'm short I ordered the petite and still had to hem them 2". It would seem that they averaged the petite length.
Overall I'm happy. The material is thicker than regular scrubs and there are sooo many pockets. These can literally be very versatile as they are not a "pajama" pant and look very professional
