Can a 16 year old get a tattoo with a guardian?

If you have parental consent, then yes, you can get a tattoo done. However, this doesn't always mean that you should. Your opinions on what you think is cool is constantly changing, especially when you are that young. You may get something tattooed on you that you think is absolutely amazing, but then just a couple years later you will be wondering why you ever thought it was a good idea.

I would just wait the extra two years and really think it over. They made the age requirement 18 for a reason.
