I have a 36" waist, 48" hips,  and got the size 34.  I really should have paid closer attention to Rago's chart, because it was too small and the fabric kept rolling up on me.  Had I gotten the size more appropriate for my hips (38), I know I wouldn't have had that problem.

Other than that mistake on my part, this garment was solidly constructed and gave me moderate hold.  It was enough to flatten out my slight lower tummy pooch.  The open nature of the item made my butt look and feel amazing too.
