How important is it to wear a bra?

I doubt going bra-less will cause premature sagging, all a bra does is lift the breasts up and it gives support. How can that make your breasts firmer? It’s like saying those shapewear support pants make your backside firmer. All it does is give the *appearance *of firmer, pert breasts while you’re wearing it.

THIS. I think a bra just gives support. Not sure where it ties in with sagging?
