Size 8. 5ft 2. Current cup size 32b

surgeon has suggested 335cc under anatomical.

Worried this is huge? It looked okwhen we tried the different sizes and I wear a very padded bra so with top on it looked no different. That’s what I want. But it’s a marked difference to how I really look minus the super padded bra. Anyone got similar stats that’s able to offer any advice?

Thanks x
