I went and got fitted 1 cycle after finished breastfeeding, but I was desperate by then. I got 2 and she said to come back in 6 weeks to get 1 or 2 more. It was amazing, I went in with my breastfeeding bras still on and they were size 14B and I left with regular bras sized 12D!! So I lost size around my body but my cups got bigger! I was fitted while pregnant with Matilda my first and then didn't get fitted again until after finishing breastfeeding my second. Its obvious I should have got some bras in the meantime....
