Hijacking to ask a similar question, as my post baby bra requirements are not what they once were (feeding plus lost a couple of stone...)
I'm 30 under (although I can get the tape measure to 27.5 if I exhale and pull it tight...) and 42.5 over. I'm short, size 14, and generally have to have straps at their tightest. I have very little breast tissue in my armpit/ round the sides - I must be one of the few women who has nothing to scoop! (I've clearly been watching these threads!)
I used to wear a Freya 34HH, 32J when I was slimmer, but often found the 32 too tight in the band. I found panache bras a bit diggy in the armpit. I'm currently in a 34J anita nursing bra. It's cups are okay, though the gore is not flat, but the back is lots too loose. It was a compromise in the world of horrid nursing bras!
