Fashion parties need more McDonalds and 7-Eleven Slurpees. And Alexander Wang knows that. Thats why his #WANGFEST Spring/Summer 2017 after-party at Pier 94, squeezed between the Hudson River and Westside Highway, was stocked with the pinnacle of junk food on Saturday oh, and perfect athleisure. The fashion designer also used this time to celebrate his new collaboration with Adidas .
