Carrie, while this may sound odd, I wear my usual "Granny Bra" (36dd makes it darn near impossible for the cute bra's.) and then I put on two sports bras. It's actually pretty comfortable, and prevents them from...well ya know.
As for them getting smaller....I was a size 7 with 36dd. They didn't get bigger, nor did they get smaller. They have always been in the way.
Hope this helps you a little.
