I was able to get a bra sized suit at:

They seemed to have lots of styles earlier this summer and in hard to find sizes. I'm a 32F so not an easy size to find and there was a lot to choose from for me! Also google for a coupon code, there are usually lots out there. You generally get free shipping over $50 and their return policy is very easy. I use them a lot for bras!
