Audrey Hepburn's classic elegance will never go out of style—especially in the hair department. Take the looks Olivia Palermo, Emma Stone, Blake Lively and Salma Hayek recently wore on red carpet for example. All have exaggerated, bumped-up volume along the crown, allowing their flawless complexions and detailed dresses to take centerstage. To experiment with a similar look, fully tease the hair along the curve of head with a rattail comb, then sweep the strands in front up and over the texturized clump. (A generous blast of hairspray will keep these gravity-defying looks from falling flat!) For more of our favorite holiday hairstyle ideas, click through the gallery.
