Whatever you decide to get, wait at least a year before getting it done.
Getting tattoos removed is a very painful process, as is getting a tattoo.
You don’t want to get something done only to find that you don’t like it six months later, and trust me, this happens to a lot of people with their first tattoo.
I’d recommend getting it done in Henna first, that way you can see how it looks on your body and how you feel about it several months later but you still have the security of knowing that it will fade away eventually.
Also take into account that tattoos are addictive and that once you’ve had one done the urge to get more can be very strong so also make sure that whatever you get will look ok should you decide to get more done later on.
No matter what go to a reputable tattooer, ideally one where someone you know has already been tattoo’d, and never go to the guy who happens to be the cheapest in your area. Your tattoo will last your entire life and you don’t want it messed up and looking stupid just so you can save a few pounds.
