Check out the FTM gear forum... lots of threads on binding in there...
But yeah, you're kind of stuck with layering, even with a binder sometimes. Under armour compression shirts work well, sports bra's a size too small, back supports, and control top pantyhose can all work and be disguisable easily enough when you buy them. And as tempting as it may seem, ace bandages really don't work that well, and will mess you up.
