460cc round nagor what size will I be? Currently small B full c. Have attached photos Of me now. (photos)

Thank you for the question. There is no accurate/reliable/predictable correlation between size/profile breast implant utilized and cup size achieved.  Ultimately, careful communication of your goals (in my practice I prefer the use of goal pictures, direct examination/communication in front of a full-length mirror, in bra sizers, and computer imaging) as well as careful measurements (dimensional planning) will be critical.
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 know words such as “natural” or "full B, small C cup” 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.

Breast Implant Size is a combination of subjective and objective
criteria.380 cc is a reasonable recommendation. There is not a direct
correlation between the cc's of a breast implant and the corresponding
cup size, as cup size is an inexact measurement that varies considerably
among companies and even within the same company. Online consultants
will not be able to guide you as well as surgeons who perform in person
consultation.The size of the implants are based on a combination
of a patient's goals and objectives and her anatomy. In order to
provide a natural looking augmentation, the surgeon needs to evaluate
many factors including soft tissue coverage, skin laxity, chest wall
width, breast imprint width, the shape of the breasts and relative level
of constriction to ensure that the breast implants are appropriate for
your body.
