This has been a problem for me for a long time.
I am large chested (38DD) and find that the over the head versions offer virtually no support, and trying to find a regular style in my size is almost impossible.
I finally found some, regular stlye and in my size at KOHL's. The brand I found that carries my size is LILY of FRANCE. And I must tell ya- they not only fit great, they keep me cool as they are absorbent, and they look great on. I actually like to admire myself in the mirror wearing only the sports bra and bike shorts and that is GREAT Motivation!
I highly recommend these bras!
