What could be more apocalyptic than the mainstreaming of neck tats? Now, don’t get me wrong: I love super-crisp, hi-def tattoos, and I love talking with owners of such tats about their tats (note to readers: most inky strangers love inquisitive, conventional types). But, neck tats! Getting the cautious imprimatur of The Times’ Guy Trebay! This is a major oy vay moment. Forgetting their gang connotations, neck tats don’t work on an aesthetic level either. Unadorned, there is already so much movement in that area — the face, the tendons of the neck, shifting necklines — that adding a permanent, static element messes with the natural flow of things. It’s too busy. So, just imagine wrinkles in the mix. Yeesh. Could neck-tatters be the next big Botox market?
