I'm just going to piss off everyone in here right now:
Tatoos are ugly on everybody, all the time, anywhere on the body. Period.
And more disgustingly--worth noting--is that they do NOT age well. Yes, I know you are 22 and independent and artistic and free thinking....
But think about this. The body that you're living in? It's the only one you get. No warranty no replacements. That tatoo on your arm/shoulder/boob/belly/butt is gonna be with you for the rest of your life. When you're 40. When you're 50. After you have aged 20 years and put on 20 pounds. And that green splotch on your leg at 35 isn't going to be cute anymore, and at 45 it's going to be hideous.
Get some felt tip markers and make art on yourself. Buy some paint and have at it. Then in a couple of days when you're tired of it and it looks smeary and stupid, wash it off.
Ladies, women, girls--please no more ugly tatoos. I'm begging you.
