I've always heard it was a bad idea to bind growing breasts. You're better off hiding them with clothing
styles. Also, there are other changes that may be noticed by people around you, just check out some
HRT timelines. Your facial features will soften dramatically, as will your skin. It ain't all about the boobs!
Eventually comes "male fail".

You're going to need a better plan than just binding.
