I am bigger than you but love Bali bras. I need support but do not like padding or underwires and I don't want any seams in the cup area. I am from the bra-less seventies era and want a bra to barely be there. Bali has one that works perfect for me. But I checked their site and they only have 4 models in 32C and they are all underwires. But maybe you can find one that you like -- their Passion for Comfort line is great.
