I love love love these.  I bought them to wear under my scrubs at work.  I just wanted something that I felt gave some support to eliminate the jiggle factor under the thin material of our scrubs we are requires to wear.  I am 5'5 148 lbs with wide hips and the medium fit well. I will say they do roll a little at the legs and waist but for wear with scrubs that is no issue because scrubs are not fitted.  not sure how they would do under jeans but my jeans give me enough support so i wouldn't use these under jeans anyway.  i work 12-14 hour shifts on my feet and these are comfortable and easy to pull up and down to pee.  so happy i found these.  even give my lower back some support.
