It's not what you think :-D
I've got this very low plunge dress to wear for an event. I was going to buy a wonderbra plunge bra to wear under it but because I'm only a B cup, reading the bra reviews it seems like the bra supports but doesn't give much shape (I dont need the support, but I do want a bit f added cleavage).
WIBU to buy some of those filets or something and just shove them in? I dont think this bra has the little pocket things
