After reading all reviews, some saying the band size is too large and some too small, I ordered my regular size (34DD) and hoped for the best. I received my bra and the band size was too large. This bra is exactly what I was hoping for otherwise, the cup size is perfect. I returned and ordered a smaller band size. If you are very busty, but also very thin, I would absolutely recommend going for at least a full band size smaller. The replacement fits perfectly, I feel supported and it's comfortable too.
