You either have it or you don't. A corset will only make the female body shape look better, not create one. Might want to ditch the baggy pants though, it makes it look worse. I recommend padded bras and empire waist dresses. Sure, they show off the legs but slim legs are better than fat ones with thunder thighs. It will also cover up the lack of hips, but again...small hips aren't so bad.
