EXCLUSIVE AT NET-A-PORTER.COM. Alexa Chung is so busy, she's rarely in one place for long, but fortunately she still found time to design a collection especially for us. Perfect for party season, this dress is cut from lustrous silk-blend jacquard and covered in polka-dots. The ruffles keep the look super feminine, while the high neck and pussy-bow enhance its glamorous '70s feel. The style maven herself told us less is more makeup wise, "maybe a little dash of silver glitter and some curled lashes without mascara."
