Labor Day—and the rain storms it brought, saturating the east coast—is the first sign that this summer is waning; fashion month is about to kick off, film festival season is underway in Venice, and celebrities are returning from their beach vacations. As the dust clears, it's finally time to weigh in: who flexed the hardest during summer 2017? Whose Instagrams were the thirstiest? It might be Bella Hadid, who ventured from Arles, France, to London, England, and Mykonos, Greece, finally ending up in Beijing, China, for a series of Bulgari events. (She made time to shoot several September covers while she was at it.) Or, alternately, it could be Emily Ratajkowski and January Jones, each of whom seemed to spend the summer wherever there was a beach. Chrissy Teigen was a clear winner; she and husband John Legend traveled to Bali, Marrakech, and Lake Como. Even Karlie Kloss was a strong contender, passing her summer galavanting across France and pausing to show a coveted look in Azzedine Alaïa's latest show. See who had the best summer, and wasn't shy about showing it on Instagram, here.
