The summer parties are in full swing this week and everyone was ready to take advantage of the warm evenings by wearing their festive best. Kate Moss, Charlotte Tilbury and Liv Tyler went the casual route in breezy dresses while singer Rochelle Humes opted for a searing pink pantsuit. Over in Brooklyn, Ashley Tisdale, Ariana Grande, and Alessia Cara channeled ’90s vibes, complete with denim minis, tube tops, and graphic tees, at an Amazon event. Meanwhile in Los Angeles, which was experiencing a heat wave, Ashley Madekwe stayed cool in a wide-leg jumpsuit and Emma Roberts wrapped herself in a gauzy black dress. Who wore the best look?
