34B to a 34D...what's the Right Amount of Cc's? (photo)

I agree with your PS's choice of 475 to 525. Silicone is the way to go as well. The 3D animation should be accurate. Good Luck.

Based on your athletic build and level of activities I think that a 475 or 525 is way too big! Bigger is not always better for all breast implant patients. Choose your size and doctor carefully. While I use both saline and silicone with a trans axillary  incision the use of  a silicone implant requires a bit of a longer incision. While I need to examine a patient to give formal advice 375cc  saline or 425cc Silicone would be the largest I would use on you. Good Luck!
