The Frog Bra is a sports bra that's 32% lycra, which is two to three times higher than most other sports bras, so it provides decent compression on its own: http://ftmguide.org/binding.html#sportsbra. Unfortunately, they've been out of production for about two years now: http://www.titlenine.com/product/310900.do.
