For the third season in a row, Tommy Hilfiger tapped Gigi Hadid to co-design his runway collection. Last spring, the model and designer took over Venice Beach for a California-inspired collection and before that, they staged a blowout carnival during New York Fashion Week. For Fall 2017, the duo designed their own tour merch, which will make its runway debut during a see-now, buy-now show at London Fashion Week. Ahead of the show, see the full lookbook for the collection, which is available to shop in stores and on starting September 21.
