Every notice those larger busted models or actresses in their late 20's SAG because their Implants are to LARGE for their bodies, and they don't wear real bras, just skimpy no support ones? That swimsuit top might as well just be a Pasty Pole Dancers wear.
I was a 5' 130 lb 40 D at 15. I'm 70 now, still wear the same 40 D, but the new bras don't support like the Old ones did.
