I bought a pair of these cargo scrubs in XS like i normally do for cherokee pants.  The XS was a bit snug on hips and almost too small to wear.  So, I bought another pair in small and they are much bigger.  I still like the pants because of the low rise cut and the cargo pockets, but I wish the XS were just a tad bit bigger.  I will buy another pair in the small size soon.
