What tattoo parlors in Florida will tattoo a 15 year old?

None should. Legally you must be at least 18 or have parental permission. And usually the parent has to be present when it occurs. If you want a tattoo I can't say anything to change your mind but as a tattoo artist, I would never put ink on someone your age. You will still grow and the skin will stretch and you will eventually hate what it turns out to look like. I can't tell you how many people come in a day to my shop that want a cover up tattoo. No tattoo artist will tattoo a person under the age of 18........ but it never hurts to ask around.
