Heya. I got measured there for a few bras, a sports bra was 34D and a strapless bra I got was 34E.
I’m a 32 back normally. I’ve been measured in boux avenue and I’m a 32E/32F (for a certain style) and I even bought a cheap primary bra and I’m 32DD there.
When she said 34 back I was a bit confused cos I’m a size 10 normally and always wore a 32 back
