What cup size is 570 cc?

Its impossible to tell what a bra size will be after a breast augmentation, everyones breast change slightly different depending on the type of implant, above or below the muscle and how much breast tissue you already had, be concerned over shape not size!

Thank you for the question.  There is no accurate correlation between size of breast implant utilize during breast augmentation or revision I breast surgery and resulting cup sizes. Ultimately, careful communication of your goals (in my practice I prefer the use of goal pictures and direct examination/communication in front of a full-length mirror) will be critical.
Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery  or revisionary 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. I have found that the use of words such as  “natural” or "C or D cup” or “porn look” 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.
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, helps.

It is absolutely impossible to tell based on the information. Implants wont change your band size. So if you were a 36 to start with you would still be a 36 after surgery. Your cup size would increase.  A rough ball park is 150-200cc per cup size.

The largest implant is 800cc's - you have already a 570cc so you can put sizers in your bra till you come to a new volume you like.  Generally you need to have atleast 50cc difference in size to see a difference.Dr. Corbin

Because breast implant retailers label the same bra different cup sizes it is impossible to tell you what cup size a 570 cc breast implant would be.  Generally speaking in the same bra make, style and shape, 200 cc of breast implant can increase that particular bra by 1 cup size.However exact relation of implant cc to cup size is impossible.For more information on breast implant size please read the following link:
