Here is the backstage of Jason Wu, for the second day of this New York fashion week. “An Asian person doing an Asian collection. It’s a revolution,” cracked Wu at a preview the day before his show, noting that he did not decide to go there thematically because China is booming. “It’s been booming for a long time,” said the designer, who lived in Taiwan until age nine and went back a year ago for the first time since starting his business. Asked if this was his most elaborate collection to date, Wu replied, “It’s my most luxurious.” Super model Coco Rocha was backstage chatting with models-friends and enjoying being a guest at the show.
