What size are you now, I’m very similar size to you and started as an a, I got 340 cc and was aiming for a c/d and at the moment I’m really happy with the results just one week p.o.
I went for the largest offered too and after seeing quite a lot of people being offered larger I did worry a bit but knew that the surgeon would know what would look good on me. if you’re unsure on sizes I think you should make another appointment just to make sure you’re 100% before your op xx
