I normally wear a 32D in most bras.  I tried this one in a 32D, and the horizontal seam was well above the fullness of my natural bust.  Maybe I just needed a smaller size cup, but with all the hooks and eyes, this was a pain to put on and take off, so it wasn't worth my time to try a different size.  Hooks and eyes wouldn't have been so annoying if I wasn't a nursing mom, but being a nursing mom, you can't make baby wait a long time while you unhook 40 (yes, I'm exaggerating) hooks and eyes.  I love the CW-X Xtra Support Zip Bra, but was only able to find ONE in my size (and not at Amazon) on the internet.  Still looking for the ideal sports nursing bra for a tiny frame, larger bust woman.

Update:  I found my perfect sport bra for breastfeeding.  The Moving Comfort Fiona Bra.  Yay!
