This is so true.
I went in saying around a D/DD he gave me 350cc
I’m 14 weeks tomorrow, I finally tired on a balconet bra which was a 32 D ( i measured myself online i inputted my figures said id be around a 30 D/E ) Me thinking this would fit.
Nope no chance ! I believe i will be at least a DD/ E possibly.
But all shops are different and so on
