You can get your belly button pierced at many different places. You can go to a local doctors office or a mall. You can sometimes get it done at a tattoo parlor too. Most people go to a jewelry store. Pretty much every jewelry store will pierce something for you. But where ever you go you have to make sure the place uses clean tools. The place you go to has to be clean and use sterilization procedures so there is no exposure to germs. Needles must be disposable and all their tools sterile. Make sure who does the piercing is well trained and licensed to operate the tools.
