Should I get 500cc to 525cc to achieve this desired look? (photos)

Hello and thank you for your question. You are a great candidate
for a breast augmentation.  The size, profile, and shape of the
implant is based on your desired breast size/shape, your chest wall
measurements, and soft tissue quality.  This decision should
be based on a detailed discussion with equal input from both you
and your surgeon.  This entire surgery
can be performed with a small incision technique.
Best wishes and good luck.

I appreciate your concern, however I would not elect to go to large with saline implants if you are still desiring a natural result.  Ask your surgeon about possible dual plane technique, as this provides some lift as well and may allow you to achieve your goals without extremely large implants.I try to tailor each breast augmentation operation to my patient's desires and body type. There are pros and cons regarding saline and silicone implants, and patient anatomy and preference play a role in selection. The same is true regarding implant projection. Be sure to consult with a board certified plastic surgeon and go to your consult with all your questions written down so you don't forget to ask something. Good Luck!
