I'm a DD or E... depending on what style/make.
BUT the good news is, I bought a lot of new bras off Ebay a while back. 75% of them were fine, but I do have some really pretty ones just waiting for me!
Although, even when I did lose 50kg 15 years ago, my DD's never got any smaller than a D.... which still made it hard to get into those size 12 dresses!! Squished boobs! Back to size 14! *sigh*
