High profile or moderate plus? At what volume? (Photo)

If you want a natural result in a C or small D cup then a moderate plus profile 350-400 cc implant would be the way to go.  You have a long chest so the increased base width of a moderate plus profile implant would be desirable as well. You already have some breast tissue so I agree that a 450 cc implant would be too much. 

Thanks for the stats. They help a lot.Let me review your expectations. You are a 34B and you want to be a natural C or small D. Your current diameter is 13cm.Here would be my recommendations based on the numbers:1) 400cc HP will probably be a D cup but would fit your diameter.2) A 350cc Moderate Plus might get you a natural C or small D and fit your diameter.3) I don't think you need a crescent lift. Your nipples are centered and pointing straight ahead.Now, plastic surgery is not a complete numbers game, so a thorough consultation would be needed. Remember, all bra manufacturers have different cup sizing and are very inconsistent. At best, plastic surgeons can only guess a cup size. They cannot guarantee a cup size because all stores measure differently.The goal of the consultation is for the plastic surgeon to understand the patient's expectations by listening to the patient and possibly seeing some images that the patient brings. After that, the plastic surgeon tries to demonstrate what certain implants might look on a patient's frame.There are several ways to do this.  The implants can be placed in a tight shirt and shear bra and the patient can see if the size matches well with their body. If a plastic surgeon has computer imaging, like Vectra 3D, he can show the patient what she might look like with certain sizes.Once the patient is comfortable with a size, the plastic surgeon measures the diameter of the breast to pick the best width (profile) in order to obtain optimal fullness and cleavage.If the surgery achieves the look the patient saw in the consult, then whatever bra size fits really doesn't matter. In other words, concentrate more on the look than a cup size. If you need more clarification, go back to your original surgeon or get a second opinion. Numbers are great, but sometimes you need to see it to believe it!Good Luck! 

At
size 32 B, each 100 cc corresponds to 1 cup size change.  If you want to be a C, it would only take 100
cc to go from a B to a C.  Instead of
doing augmentation with implants, I recommend a breast lift with fat
transfer.  There is a new technique
called The Bellesoma Method, which will reshape your breast tissue creating
upper pole fullness without implants, elevate them higher on the chest wall and
more medial to increase your cleavage. 
Vertical scars are avoided, nipple sensation and the ability to breast
feed are maintained.  At the same time or
later, fat transfers can be performed if additional volume is desired.  400 cc to 450 cc implants are huge, not stable
and will descend.Best Wishes,Gary Horndeski, M.D.
