Red carpet wrap: Olsen, Swift, Cole and Wilde

From Elizabeth Olsen, to Olivia Wilde - the best and worst of this week's red carpet fashion.

What does one wear to a Chanel, The Little Black Jacket — Karl Lagerfeld Photography Exhibition dinner party in Milan? Why, Chanel of course. Little Olsen sister Elizabeth shows how to do head-to-toe black designer and still keep it young.

No-one does metallic gold quite like Taylor Swift and she wowed at the 48th Annual Academy of Country Music Awards in Las Vegas in this Dolce & Gabbana number, with Jimmy Choo shoes. The demure neckline was balanced by a cutout back.
