What's the size and profile of implant whose BWD is 14cm and ribcage is 27? (Photo)

There are a variety of implants available that would fit that breast diameter. If you choose in the 375 cc implant you should end up around a D cup. However the breasts in the picture are DD breasts. If you want to see a of with 375 cc implants look at the example on my site and consider how much breast tissue you have compared to you because she has a similar height. I also have some excellent educational videos regarding breast aug. 

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 D and a 38 D are significantly different. Cup size varies from
manufacturer to manufacturer and even within styles from any particular
manufacturer. There is also no
direct correlation between an implant size or shape and resultant cup
size.

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 that your plastic surgeon
be 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.

The pics you show are a DD and are no way a C cup. The pictures you like  and what you say you want are not on the same page so I would imagine that your doctor is going with his or her best judgement. I would think a 400 - 425cc moderate plus silicone would be about right. Good Luck!
