Doctor suggested 470cc Ultra High Profile, will someone describe what my outcome may be? And info about UHPs? (Photos)

Thank you for your question.  It really depends on the look you want.  According to your photographs, you seem to want a round, full look, and 470cc UHP will certainly give you  that look.  My suggestion is to try on sample implants to get an idea of how it will look.  In my experience, that is the way to determine the best implant size for you.

Thank you for the question and pictures.  Based on your photographs, I think that you are starting at a good place and should have a very nice outcome with breast augmentation surgery.  I also think that your goal photograph is realistic understanding of course that goal photographs are communication tools not guarantees of exact outcome.
 Online consultants will not be a good resource for you when it comes to selection of appropriate breast implant type/size/profile.   Although it is true that ultra high profile breast implants have greater projection,  I do not think that anecdotal opinions you have received online are necessarily relevant in your case. In other words, there are many factors that come into play when it comes to the final look achieved with  breast augmentation surgery.  Anecdotally, I have found that ultra high profile breast implants are very useful when it comes to achieving certain outcomes for patients with narrow frames.
***Given that your surgery is coming up soon, I would suggest that you spend additional time communicating your goals/concerns directly with your plastic surgeon, preferably prior to the date of surgery.
  Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery ( regarding breast implant size/profile selection) is:
1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. ***Ask to see lots of examples of his/her work.
2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. 
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. For example, I have found that the use of words such as “natural” or "C or D cup” or "look ridiculous" etc means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup size may also be inaccurate. Again, the use of computer imaging has been very helpful during the communication process, in our practice.
3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery, after the use of temporary intraoperative sizers.
I hope this (and the attached link, dedicated to breast augmentation surgery concerns) helps. Best wishes for an outcome that you will be very pleased with.
