I really love the Miraclesuit Corsette with Firm Control and the Flexees Torsette Slimmer:

I like them because of the straps, the hook and eye style down the front (I have wideset shoulders, pulling something over my head just aint gonna happen lol), how I can wear my own bra (and it will work with my scoopneck cut dress) and because of how comfortable they are.
BUT, I need something with a low back-- has anyone found something like the torsette shapers that has a low back? TIA.
