My Right Nipple Isn't Round?

You indeed paid a lot of money to look good. If your dissatisfied with the appearance of your breast it should be brought to the attention of your surgeon will do everything he can to make you happy.

Tell your doctor you are unhappy with the shape of that side, but realize that he or she may not want to do any kind of revision for 6-12 months since things change so much after surgery. There may or may not be charges. Every office has it's own policy. 

Don't panic! Adjustments are often necessary after cosmetic surgery and few surgeons would charge for them in the first year. After all they want you to be happy and refer your friends! They may even want to feature your boobs on their website.

Few nipples are entirely circular, but if yours are completely out of whack it is a simple matter to correct them under local anesthetic in the office. It is appropriate do do do this at 6 months to allow scar maturation and wound settling.

As others have said, you should communicate with your surgeon and listen to his/her advice.
