I'm a size 12 (size 16 wedding dress) and my bridal gown goes great with my figure, but my stomach tends to pooch out just a bit. I've been working on shrinking it with exercise and strength training but I was wondering what kind of undergarment I should wear. I had bought stomach trimmer shorts, but they went down to almost my knees and i don't want them to show when my fiance takes off the leg garment. I have a low v- neck and low v back in the dress. Any ideas?
