Tattoos have become like sex. They are being used to market everything from universities to designer label clothing. Ink has truly become the new black. Long before savvy marketing execs jumped on the bandwagon and made the whole thing mainstream these tattoo girls were doing it for themselves and covering themselves with pretty ink.
For the first half century after tattooing became commonplace there were few tattoos for girls. In fact, except for the small handful of rebellious women, very few females got tattooed at all. But, all of that changed about twenty five years ago when tattooing became more socially acceptable, largely due to the many celebrities who publicly sported tattoos. Some of these were women, and so the female tattoo became more common and acceptable. Nowadays you see a whole genre of tattoos for girls.
