Hosted by Coach along with Friends of the High Line, the event was not only a celebration of the brand—guests like Mara, Russell, and Moretz carried bags by the label—but also a fete for the incredible park that brings joy to New Yorkers and tourists alike. This year’s party included design and décor that gave a nod to the decadent nightlife of the '70s, and the evening featured music by DJ Kayper as well as an exciting surprise performance by world-renowned De La Soul. As the temperature cooled down, partygoers moved to an exclusive after party at The Cabanas in the nearby Maritime Hotel to close out the night. Want more?
