So just a disclaimer before I begin...I am very embarrassed to ask this question but if I don't, how else will I know? Okay, here goes: I have a pair of the higher power Spanx, and really really like the slimming effects under my fitted jersey dresses. But...I drink A LOT of water and it is a royal pain in the behind to always be pulling those things up and down. There is a gap in the crotch area of these Spanx...is that just by design or is it really to use the restroom and not have to adjust the Spanx??? Thanks in advance to answers to an embarrassing question!!
