Silicone CCs in order to go from a small B to full C cup? I'm about 5'3", 120lbs. (Photo)

Something in the 300-3500 cc range should get you into a C cup.  A high profile implant should fit your chest wall nicely.  Again, just a rough guess and best to be fitted by your surgeon prior to surgery.  Best wishes!

At
size 34 B each 100 cc’s of implant corresponds to 1 cup size change.To achieve a C would require 100 cc
implants.I always recommend small round
textured silicone gel implants placed retro-pectoral since they look and feel
more natural, are more stable, less likely to ripple or have complications
needing revision.Implant profile is
irrelevant in the retro-pectoral position since the muscle compresses it.Best Wishes,Gary Horndeski, M.D.

The best cosmetic
result in any particular breast augmentation patient depends on a variety of
factors, including: your individual anatomy, desired result, realistic expectations, a thorough
discussion with the plastic surgeon about the options, and an understanding of
the pros and cons of any particular implant choice. Proper sizing is not just
about the number of cc’s. The thickness of your tissue, breast dimensions which
include the width, height, and projection, as well as chest wall width all need
to be considered when choosing an implant. Trying on implant “sizers” of
various shapes and volumes while wearing a tight t-shirt, bra, or bathing sit
at a preoperative visit will help you and your surgeon choose the optimal
implant.

There are no manufacturers' standards for cup sizing in the bra industry. The
cups of a 34 C and a 38 C are significantly different. Cup size varies from
manufacturer to manufacturer and even within styles from any particular
manufacturer.

Keep in mind that following the advice from a surgeon on this or any other
website who proposes to tell you exactly what to do without examining you,
physically feeling the tissue, assessing your desired outcome, taking a full
medical history, and discussing the pros and cons of each operative procedure
would not be in your best interest. I would suggest you find a plastic surgeon
certified by the American Board of Plastic Surgery and ideally a member of the
American Society for Aesthetic Plastic Surgery (ASAPS) that you trust and are
comfortable with. You should discuss your concerns with that surgeon in
person.
