Hi guys!
Well...maybe this can give you an Idea....
The largest implant you can buy "over the counter" at this time is 800cc's. Mine are over filled to 850cc's, but unlike Ms. Pac, I started out as a small "b". So basically you can add these onto her, and it should give you a rough idea, although there are alot of other factors to consider.
Remember, I am 5'9", and if I'm not mistaken, Ms. Pac is alot shorter. My guess is if she were to ever go for it, she would be HUGE. Hope this helps.
Love ya! Jane
