Okay, let me just say it is an incredible gymnastic feat to pull this onto your body.  I have been wearing generic 'Spanx' for years to smooth out bumps and what-not, but nothing has ever been a challenge like this.

I got some good advice.  Buy a size too small.  I would have been inclined to buy a 1X, as I wear a 14 or 16 dress size; but I went ahead and bought the XL.  Seriously thought about buying the L... Anyway, buy the smallest one you can possibly justify.  This bad boy will suck you in, tighten you up, and absolutely correct your posture. Plus, if you are top heavy this thing is amazing because you can WEAR YOUR OWN BRA!  None of those absurd, flimsy little bras built into body shapers that leave you bouncing more than Baywatch.

The straps to your bra are tricky at best.  Very thoughtful though.  Going to the restroom is a challenge of your grace and athleticism, but can be done.

Overall, I would say a definite yes to another of these.  Girls, we jiggle!  This will make sure you don't.
