With barely a second to catch her breathe following the Khaite runway show a few days earlier, Gucci gets ready for part two of her New York Fashion Week journey. Up next: Designers Kristopher Brock and Laura Vassar's Brock Collection show inside the grand ballroom of the Pierre Hotel in New York City. Here, she reveals what really happens at a pre-show makeup test and turns the camera on the backstage mayhem. Also caught on film? A game-changing makeup trick for healthy looking brows that works off the runway, too: a quick sweep of Lit Up Highlighter through the arches with a makeup brush for the glossiest and most gorgeous finish.
