We went to prom with Kate Young last night! We were just one of the celebrity stylist’s many dates—along with her guests-slash-clients Kate MaraMichelle Williams, and Maggie Gyllenhaal—for an evening that included disco balls, pink champagne, and streamer-covered bleachers at the elementary school-turned-event venue The Old School in New York to celebrate the new Kate Young for Target collaboration. “The collection was inspired mainly by the magic of getting dressed up and the feeling of hope that comes with putting on a fancy dress and going out for an evening,” Young told InStyle.com of the line, which is full of pieces for every spring party, from weddings to prom. Gyllenhaal, along with the rest of the star guests, served as celebrity models showing off the designs while grooving to tunes spun by DJ Atlanta de Cadenet Taylor, daughter of Duran Duran’s John Taylor. “[Young’s] own personal style is really down to earth, smart, and sexy,” said Gyllenhaal. “It really comes through in the clothes.” Shop the festive collection at Target stores and online at target.com on April 14.
