I'm a 34DD or 34E. Small frame, large chest. I don't think 34 is too uncommon nor is DD or E, but for some reason those two together is difficult to find. I couldn't find anything local, even at the bra outlet store in my size, let alone something comfy. So, I went to birthandbaby.com to find a bra that fits. They have $1 shipping and a very liberal return policy and a large selection. So, you can literally try on several different bras until you find the right fit. I ended up with the new medela bra.
Can't help much on the tops, most of mine still fit as I'm not much bigger than before jr.
