It's goth, it's scary, and it was one of the biggest beauty trends of the year. Seen all over the fall 2006 runways, the polish of choice Chanel's Black Satin became a de riguer look for everyone from the ladies who lunch to the louche late night crowd. It's a throw-back look to the 70s punk era, and, frankly, to the mid-90s when Chanel made a splash with their deep burgundy Vamp. But black is definitely the new black when it comes to nails.
