It is my first post, so I want to salute all the people and request excuses by my bad English.
Whit years of boob lover experience, I see many womens go bigger. And apparently you can go bigger like you want.
I think that expanders will be the best trade. You can get 3500 cc's expanders and fill them to 2000 0r 2500 cc's; if want more in future, can fill again.
Good lock.
