I already own two very cheap items, and they actually work very well, but they always roll down to the waist and dig in. Have any of you tried the spanx with straps that attach to your bra? I was hoping they would solve the problem, but they're $75. I would gladly pay that much for a perfect bra, but maybe not for glorified control top hose, unless they're a lot more comfortable than what I have now. Do you know of any other brands with firm control, that don't roll up on the leg or down on the waist?
