Looking every inch the fashionista, Blake Lively hit the red carpet in a divine fringed and embroidered Twenties-style frock by Marchesa. She was joined by her Hicks co-star and budding style maven, Chloe Moretz, who sported a patterned minidress from Stella McCartney’s forthcoming spring/summer collection. Don’t they look just like sisters in style?
