Rather helpfully the hangers they use for the clothes in Target have colour coded sizes on the neck of the hanger to make it easier to tell what size you're browsing. Rather unhelpfully they are often the wrong size for the garment. Especially the bras. Went to try one on that I thought was a 14C* (we live in hope, OK?) only to find it was actually a 10F!!! Mind you, I didn't realise that until I had tried it on, or attempted to...no way that band was going around my chest. And the cups!! Whoah momma!!! I was pretty disappointed at first until I realised!

Anyway, I went and found an actual 14C and a 16B (what I've been wearing the last few months)...I'd heard that if you go down a band size you can go up a cup size, and I've noticed in addition to an increase in boobage that my torso is getting slimmer as I lose muscle. Annoyingly neither fit. Way too much room in the cups for a 14C (

) although the band was OK and the 16B was not great either. So I grabbed a 14B and Lo! it fit very nicely.
Bra fitting is apparently a very arcane science!
*Aussie sizes, I think 14C equals 36C US, 10F = 32F, 16B is 38B &14B is 36B.
