Tattoos done properly are a story of your life worn on your skin.
For one thing, no 14 year old on the planet has lived enough to have a story worth wearing...
I have a strong appreciation for body art and the guts it takes in adulthood to rock it. If ever I see someone that has clearly had a lot of work done that clearly is on the mature side (and not some poseur punk) I ALWAYS compliment it-- even if it's not exactly my taste.
Here are my rules for tattoos.
1.)If you are too young to get a tattoo on your own (and able to pay for a good quality work) you are too young for a tattoo. Period.
2.)If you want to get a tattoo, choose your design. Then print it on a piece of paper and hang it up on your bedroom wall, or frame it for your dresser or nightstand. If you still like it in a year of looking at it, then you can ink it.
3.)Money is no object. Interview your shop and artist like you're marrying them ('cause in a way, you are!) Grade them on safety, sanitation, and all licences up to date with the health department. Ask to see a portfolio of the artist's work. Heck, google them for online reviews. There is no such thing as a "bargain" tattoo. Choose an artist who has done jobs similar to what you want before.
Let some other poor fool be their "learning experience". Go pro. ALWAYS.
4.)Take every precaution... if there are any letters, symbols or words in your design insist on the artist taping a paper copy up in view so he can double check every.single.detail. Don't assume they know how you want to spell "Mary".
5.)Take your lifestyle and interests into account. Sure, a kid may just work retail at Hot Topic now... but is that what she wants to do forever? It's good advice to have a "plan" to cover your ink in case you need or want a more professional career someday.
Want a cuff? are you cool with wearing long sleeves to work every single day year round? want a calf design? abandon all hope of wearing business casual skirts...
6.)Also take into account if you really are cool with having people make snap judgments about you. Not only in judging the image you chose to brand yourself with, or the fact that you have ink at all, but are you prepared for people misinterpreting what your tatt means?
Is it going to sting if middle aged women clutch their purses tighter when they see your cool tribal design? If teenage girls cross the street to avoid you because they think your crown of thorns tattoo means you were in prison? Or if the mother of the boy you might want to marry thinks that confederate flag on your ankle means you're a bigot?
Yeah... these are all too deep for most 20 year olds... much less someone who doesn't even have a drivers permit.
I've been on the fence for years because I'm not willing to risk getting an image that I outgrow as I leave behind hobbies and interests etc. I only just figured out a design I want and think I can live with long term back in July at the age of 29. I'm still on the one year waiting period
