Im usually a 34f/g or a 36f- I usually size down in things you buy strictly on band size otherwise I get no support. The 34 band fit like a 36 right out of the package. It offered me no support and the cup area was very very short, barely covered my nipples. The straps didn't dig in which was nice. I had hoped that this would keep the girls separated like in the photos but did nothing of the sort and I continued to get the grossness, sweat, bumps, and breakouts between my breasts due to this. Wore it once and threw it out.
