I wear black nail polish sometimes.
I ran into my childhood piano teacher. It took her a moment to recognize me. When she did I was greeted with this, "Black nail polish!"
One of my kids called me emo and wanted to check my wrists for cuts.
Black nail polish is high fashion, not a sign of a disturbed mind. To support my thesis, a brief history of black nail polish. In ancient China black and red polish were reserved for royals and was ultra hip in the sixties and seventies. In the mid and late nineties the beautiful black polish was usurped by scary creatures such as Marilyn Mansen, heaven help us. But then Gucci models sported it and Chanel came out with a version (running $100 a pop) and everything was ok again. And I've seen Stacey London wearing it. Granted, the black does give a rebellious air but I think regular, chic people can pull it off. So let's just own the black nail polish.
