350, 375 or 400 ccs? (Photo)

In my opinion, based on your ht/wt and breast width, the 400 range in high profile will likely be the best neighborhood.  Ultra high 500cc implant in my opinion will look a bit ridiculous, but there's no accounting for taste, so you'll have to go with your gut on this.

Choosing the right size implant depends on any number of factors all of which require an in person exam. However, in my opinion, the 460-500 are too large for someone of your size, but the final decision will depend on your desired outcome. Best, Dr. Nazarian

Hello,Thank you for your question and photos. "Too big" or "Too small" can be very subjective, however Ultra high profile implants in the range you mentioned will be a more augmented, obvious look for you. My patients find it helpful to try on the implants sizers with a form fitting t-shirt in the office so that they can see the volumes on their body and get a feel for them. 350-475 on a base width between 11-12 will be fairly significant. I recommend that you talk more with your Plastic Surgeon about your Aesthetic goals and Sizes in your range.All the best
