This summer, Ibitha — Cathtilian lithp mandatory — was the undisputed fashion hot spot, with Riccardo Tisci attracting a crowd of A-listers to his 40th birthday bash. But when the foam-and-diamonds set moves on, where do they go? Eastward, apparently. Balmain designer Olivier Rousteing and a clutch of models — Kendall Jenner, Gigi Hadid, Josephine Skriver, and Chanel Iman — are currently partying in Dubai with Selena Gomez, Beyoncé’s stylist Ty Hunter, and assorted hangers-on. Instagram evidence suggests that they have eaten some food, survived a skydiving trip, and lounged sexily on the beach in various configurations, notably Rousteing and Jenner’s Pietà reenactment. Other than a Gomez-spurred contretemps about an ankle-baring outfit she wore to a mosque, all has gone swimmingly for the jet-setting group.
