I went for a bra fitting yesterday. I walked in wearing a 38C and walked out wearing a 36DD (same brand/model# bra, as it happens).
People have made fun of me my whole life (friendly teasing, that is) because of my tiny boobs. DH was cracking up when he found out his wife was a DD.
Considering I still have bras from college (probably 34B), I'm thinking I should just purge the whole bra drawer, see how these industrial things hold up for everyday use, and maybe get a couple of pretty ones at the VS semi annual sale this summer.
