So....for ladies who wore spanx. How difficult was the potty process? My dress is a fit and flare. I just am having a hard time picturing holding the dress up, rolling the spanx down, etc. Is it as bad as I am picturing? I was looking at getting the ones that go from your thigh to high waist and then just wearing a strapless bar. Would it be better to just go with a longline bra? Which is more comfortable?
