I would say C-cup is perfect, B-cup I could live with, A-cup well... That remains to be seen...
This applys for a long term thou.
I have never held in my hand a plastic piece of boob however it looks damn fine so I would prefer a girl with a boob job rather than a A-cup.
Nevertheless if you feel comfy with your size and if your guy is happy too, then there is really no reason to go through it. Boobs are not everything you know...
