I wore a Spanx Open Bust Vest for a few years - I just tucked it into my trousers/skirts as you would a normal vest and it meant I could wear my normal bra, including plunge bras.
They don't do them anymore 🙄. They've been replaced with something similar, but with a stretchy material across the bust area which is no good for anything with a deep(ish) v-neck. Does anybody know if any other shapewear company makes them? Spanx still do some Open Bust products but I don't like anything that has crotch poppers or I have to half undress myself every time I go to the loo.
This is the link of the Open Bust products they do do, in case anybody's wondering what on earth I'm talking about.
