I have a low back dress and need some hold in underwear. Can anyone suggest any? I'm struggling to find something that will work with a low back. Thank you

My still new Bernina helped a ton, as did its walking foot and straight stitch plate (a plate under the presser foot with a small hole instead of a wide rectangle opening - it means I can't move my needle or do zig zag stitches with that plate on, but it makes it much less likely that delicate fabric will get pushed down into the machine)
