The London rain always seems to disappear just in time for the Serpentine Gallery Summer Party. And it wasn’t just the weather that made it a hot night on the lawn of Kensington Gardens. Kate Moss and the 18-year-old Jean Campbell arrived early to enjoy the last rays of sun and were welcomed by Tommy Hilfiger (the evening’s host), Alex Katz and Michael Bloomberg. (This year’s pavilion, made of fiberglass boxes and designed by Bjarke Ingels, looked even more spectacular with that sunset.) Peter Pilotto and Christopher de Vos, the two designers behind Peter Pilotto, exchanged notes with Erdem Moralioglu and Emilia Wickstead (talking Brexit’s effect on fashion, maybe?), while Ron Arad chased a waiter with mini burgers on a tray. By the time everyone had said hello to each other, the sun had gone down and the music volume went up, with a live performance by Calypso Rose, the indisputable and irrepressible Queen of Calypso since the 60s. Naomi Campbell danced with Astrid Munoz and Elisa Sedanoui, while Tom Dixon chatted with Adwoa Abdoah and Bianca Jagger. When Jenny Bastet and Josh McLellan-Ludlow started to DJ, the real party was on with Georgia May Jagger, Gareth Pugh, Marc Quinn and Peter Saville on the dance floor. Around midnight, Grayson Perry was spotted unlocking his bicycle to head home, as one does on a nice summer night.
