Gigi Hadid promoted the latest fall-winter Tommy Hilfiger collection at a department store in Milan. Hundreds of fans showed up for the event and she took selfies with a lucky few. Milan Fashion Week was in its third day on Friday and Hadid is definitely one of the "it" models headlining the week of fashion events. She's already walked runways for Moschino and Max Mara, where she was also joined by her fellow it girls, sister Bella Hadid and Kendall Jenner.
