Would a full C cup be ok for my frame?

Unfortunately,
you have not told us your bra size just your cup size. If you are 32 or 34 each 100 cc’s of implant
corresponds to 1 cup size change. If you
are 36 or 38 each 200 cc’s of implant corresponds to 1 cup size change. From this, you can compute the volume
required to achieve your desired goal. 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. However, since you
have had 3 pregnancies and were size C, you have excess skin, drooping and you
may benefit from a simultaneous lift. I
recommend a new technique called Breast Augmentation with Mini Ultimate Breast
LiftTM. Using only a
circumareola incision it is possible to reshape your breast tissue creating
upper pole fullness, elevate them higher on the chest wall and more medial to
increase your cleavage. Through the same
incision, implants can be placed.
Aligning the areola, breast tissue and implant over the bony prominence
of the chest wall maximizes anterior projection with a minimal size
implant. Best Wishes,Gary Horndeski, M.D.

There are many factors involved in choosing the correct implant to achieve the size you desire. The dimensions of both your breast and your chest as well as the amount of natural breast tissue must be considered.  My best advice would be to find an experienced Board Certified Plastic Surgeon who you trust that can show you many before and after photos of patients similar to you in height and weight.Best of Luck,

The best cosmetic result in
any particular breast augmentation patient depends on a variety of factors,
including: your individual anatomy, 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 32 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
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.Robert Singer, MD FACSLa Jolla, California
