Can I achieve a rather big, but "natural" look with the 2 options that was suggested to me by a PS? Hoping to be D/DD

It is my opinion that 500 cc High Profile breast implants in the partially subpectoral space will give you just what you are looking for.  Ultra High Profile breast implants will give you the phony look you were trying to avoid.  Congratulations.  You have begun your journey to having a great breast augmentation, and the size and shape of breasts you are hoping to attain.  Your breasts point to the outside because you have a relatively narrow chest for your height, and the breasts follow the curve of the ribs.  The good news is that 500 cc high profile implants will act as an extender of the anterior portion of your ribs, therefore turning your nipples back so they don't point quite so far to the outside.  Even larger high profile implants will have a greater base diameter, therefore giving the impression that the nipples are even more centered.  However, it's a tradeoff and you may not want the increased size of your breasts overall.  Unfortunately, mid-range implants (moderate plus) made by both American manufacturers are under filled.  The implant themselves, being more flexible, will follow the curve of your ribs leading to nipples pointing even more dramatically to the outside.  There are many variables you need to discuss with your Board Certified plastic surgeon:  route of entry, increasing the dual plane to get rid of your minor droop, above or below the muscle, etc.  Be sure all the necessary questions are answered during your consultation.

Your breasts have a nice starting
shape, and in my opinion, you would do well with a moderate profile gel implant
that fits your breast measurements. Using 500 ml high profile implants will likely
not give you a natural slope. . . Most of your wish photos have the
"half cut melon" look for sure. To help clarify your desires and
goals, I would suggest 3D imaging so you are sure your expectations will be
met. This operation is something you want to get right the first time. Thanks
for sharing.

Thank you for your question.  The Ultra High Profile implants are going to give you the most projection, and aren't necessarily made to give the "natural slope" you mentioned.  It may help you to see other patients who have had similar implants with a similar body type to you.  This obviously will not give you an exact idea of what your results will look like, but I would request to see a Before & After photo album for you to get a better idea of the look you can get with the ultra high profile implants.It is also to remember what you fill most comfortable in.  If you are wanting a larger size and fuller breast, that may be why the doctor suggested the ultra high profile implants because you can get more volume with those than other implants, especially when you have a smaller frame.  If you would like more information regarding breast augmentation, you can download a free copy of my Breast Augmentation Planner at ABetterBreast.com.Good luck!
