Hi Jade
I’ve just recent revision a week ago now (reaugmentation, uplift and smaller areolas) I have 450cc HP unders.
So before my 1st BA I would say I was a big B/Small C and I now I am an E!
My friend though had 375cc unders (6 weeks ago) and she was as measured is a DD! She was an A before hand.
Hope that gives you a better idea for yourself!
