If you can spend and are busty, I found that the English and French brands give much more support. I was wearing a 40 DD, when I was properly fitted at Nordie's and found my actual size was 36G. I was able to find bras there that let me wear things I never thought I could like tank tops. I got a reduction, but I still wear the brands I found like Fantasie of England. BareNecessities.com has sales all the time and I just order what I want from Nordie's at better prices. They go all the way up to N cups. It really is worth paying for the support. My back thanked me.
