What size do you want to be?
I’m 5ft 0” and 7 stone. I went straight in and asked to be a 32d from 32a. He recommended 300cc high profile which is what I had in the end and am now a 32d. I was told I could have gone as big as 400cc.
It depends on your expectations. 300cc were perfect for what I wanted and I’m very happy with the result.
Good luck!
