Have you tried compression leggings? Shapewear like spanx? Those spandex "waist cinchers" that the Kardashians have popularized?

I'm not familiar enough with various brands to recommend a specific ones, but those are some good starting places. Good luck and post some pictures for us if you get the chance!

High waist shapewear.

If you have a lot of loose skin on your torso, something like above won't work because it migh push the high skin up creating a bulge, if that is the case you need something like this that takes care of the whole torso.
