Poucho, I've been scouring youtube and found a video by someone who swears by Spanx, or something similar to Spanx. It covers from above the belly button to the groin or hip flexor area which, pretty much, covers the bag. She showed the Spanx and then covered it with her quite form-fitting top and you couldn't see the outline of the bag at all. She said she got them at Target and they were about $25 each. She has about four and rotates them as they others are being washed. If you get them in a larger than usual size, then they won't be super tight cause that's not what you need them for. Hope this helps!

I wear a Comfizz wrap to flatten the bag. The wraps are snug, so I ordered one size up to get the right fit.
