550 Cc's High Profile for 5"0 Too Big? Porn Star Look?

A large implant is not a substitute for a lift which you may need but it is difficult to recommend based on your description. Try sizers on for a day and get a feel for the volume.

Your breast implant size should complement your overall frame and hopefully bring better proportion to your physique.  If you are 5 ft and 115 lbs, I feel that a 550cc implant may be too large for your body. This is difficult to answer however without seeing photos.  There are studies which show that women with larger implants (like 550cc) tend to have more complications in the future due to the excess weight of the implants and due to thinning out of their natural breast tissue.

I prefer to use 3D imaging to demonstrate to a patient what they may look like with a specific size implant. I find this to be very useful for the patient to preview what they may look like before surgery.

Best wishes,

Unfortunately, it is almost impossible to judge what the appropriate implant size is for someonewithout seeing them and doing a full examination.  Based on your height/weight, 550ccsounds on the larger side, but it all depends on your frame, breast tissue, desired size, etc.  If you have any doubts, then meet with your surgeon again or go for another consulttaion and see what another opinion is.
