Yep
I buy matching Bra and undies! I am a DD cup aswell, I buy them through UnderCoverWear, the bras are about $39 each but they are brilliant,supportive and last a long time, i would rather spend money and get quality instead of quantity.

As for when AF is visiting i wear just Black undies and i have a few black bra's just plain ones that are convertiable.

I have bought a couple of Sports bra's and i hunted high and low for a nice pair of pale blue undies that i like.
