If there’s one haute boîte that’s defining summer 2017, it’s the Eleven Madison Park Summer House, also known as a pop-up, in East Hampton. After kicking things off in grand fashion with Keri Russell, Saks Fifth Avenue, and Vogue during the extended July 4 holiday weekend, on Friday, fashion fans were treated to an elegant ladies’ lunch hosted by Jimmy Choo, Vogue, and Athena Calderone. Joining in the celebrations were an equally stylish crew including Molly Sims, Nell Diamond, and Jessie Rudin.
