For your sake, please don’t!
Ace bandages get tighter as the day wears on. They will slowly constrict around your chest like a very flat snake and eventually crack your ribs.
Duct tape is inelastic, so breathing with it is even more likely to bruise or crack a rib. It’s not designed for skin contact and will irritate the hell out of your skin. When something goes wrong and you’re in severe pain, it will take far too long to peel off.
As for sports bras: the tight elastic in straps, hems, and underbust bands is not meant to actually compress your chest. Applying narrow bands of pressure around the ribcage creates a real risk of rib dislocation.
We know these are all very popular ways to portray binding; we’ve seen all of these in webcomics, comic books, manga, music videos, TV shows, movies, the whole field. We make binders so that you can feel as good about yourself as you felt about that one character, without the attendant health risks.
