I followed the size chart, did a measurement prior to ordering. I am 5'6", 136 lbs.(39.5" hip)  I originally bought the size 11 based on measurements but returned them when they were too large for me. The size 9 that I bought fit great. They are about an inch too long for the way I want to wear them, but that is an easy fix (hemming them up an inch is easy). Nice material with a little stretch, fit at my waist.
