I have a set of high-end silicone breast forms. You can use medical adhesive to literally glue them on and go braless if you want.
Breast plates do provide great cleavage, but I want to feel my head and my blouse. I don’t think a chunk of sweaty latex would make me feel pretty. Plus, no 60 year old gal goes around with her tits popping out. Dressing like that would clock me in a heartbeat.
