​I'm 5'3 and 115 lbs, how big should I go for my Breast Augmentation?

I use a technique called dimensional breast augmentation which involves taking in a number of factors and measurements, so each patient is unique. That being said, given your height, weight, and your activity level, along with the fact you are considering a lift, I would say you are probably not that far off in choosing an implant in that range. Best thing to do is to see a qualified plastic surgeon that has good breast expertise.

Congratulations on your upcoming
breast augmentation, and thanks for your question. It's common for patients to
have a hard time deciding on implant size, and it's difficult for doctors to
make good recommendations over the Internet. If you haven't yet, now is a great
time to visit your surgeon for a sizing appointment. At our practice, Plastic Surgery Specialists, we have a 3-D
Vectra imager that allows you to see how you will look with implants of
different type and size We find it takes the guess work out of making this
decision.. Good luck!

The only way to better understand the best size and shape breast implant for you requires that you work with your board certified Plastic Surgeon. After a thorough discussion of your desires and after a complete physical exam, you and your Plastic Surgeon should be able to start the sizing process. In my office this involves determining the best width and height and projection of implants that will not only fit safely under your skin, breast and usually muscle and but would also allow you to look enhanced naturally and achieve your goals. We now have thousands of implants to choose from, so be sure you feel confident that the implant shape, volume and projection will best safely accomplish your goals. Good luck!
