Once New York fashion week is finished, you can kiss nail art goodbye. In Milan, rarely is there even color on the nails let alone a fancy design. And Chanel Le Vernis is Ballerina is by far the most popular polish shade backstage in Paris. So at Thierry Mugler yesterday, when manicurist Marian Newman told me she was adding designs on the nails, I was stunned. It’s like seeing a unicorn—it just doesn’t exist here. In typical French fashion, however, the nail art Newman created was incredibly understated and elegant.
