VERY odd fit!  I'm 5'8, 140 lbs, normally wear a 6 in clothes, or small-medium in workout pants.  Ordered a Large after reading all the reviews. Waist/ hips wayyyyyyyy too big, even with drawstring cinched up. From the thighs down, the pants were so tight I could barely get them on.  They are cut in a large triangle shape if you can image that.
