Help, ladies! I am 5'6" and a size 4/6. My strapless fit-and-flare dress has a built-in corset that shapes my waist, and the corset ends just below my belly button. It's tight, so it presses into my lower belly and gives me a noticeable pooch.
What kind of undergarment will smooth this over, WITHOUT making my butt smaller/flatter? My behind barely works with this dress, any flatter and I would look ridiculous. And yes, I do what feels like hundreds of squats each week. That's the only reason I can barely fill out the dress. I've tried Spanx, and they work for the belly, but turn my rear into a pancake.
Ideas? Anyone else had this issue?
ETA because typing on my mobile = dumb autocorrect.
