I finally clicked on one of the bra threads and was shocked to hear that there's only ever been one true A-cup on here.
I have always thought of myself as a 36A. But, I tried the measuring thing and got 35" X 38".
Could I really be a 34C??
Well, I tried one on at Asda, and it fit much better than I would have ever imagined. It was a little tighter than I'd like, but the cups were perfect. A 36C wasn't as smooth a fit. I didn't have time to try on other styles. But, when I get the chance, I am going to find a bra that is suitable in a 36C.
