Will 450CC moderate plus profile get from 32A to 32 full C or small D cup?

hello thank you for your question and provided information as well.. based in your question its difficult evaluate you if the case dont have a picture, my recommendation is get  a consultation in person with a plastic surgeon to discuss all about theme.

It's really difficult to answer your question without examining you because 450 cc's will look different on different frames.  Also, bra sizes vary from company to company so it's not a very accurate way of picking a size.  I recommend seeing a plastic surgeon for consultation to see what size is best for you.
