Hi there, lovely! A bit of a Googling tells me that a 10E equals a 32E US. While I’m not up on minimizer bras as such, my full busted friends tell me that once they find a bra that really and truly fits, they don’t feel like they need a minimizer anymore. And a good fitting bra is the first thing I recommend to all my readers, no matter their size.
I’d recommend checking out my article on 10 bra brands for full busted women. They’re all internationally renowned for giving amazing lift and support, and that’s a good place to start.
