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.

Someone clearly wasn’t in the mood for dressing up for the Disconnect New York screening. The ill-fitting skirt, hairy jumper and ‘fat day’ tights do nothing to hide the bed hair, grumpy expression and frumpy shoes. She’s meant to be a supermodel!.

Super-skinny Cowboys and Aliens star Olivia Wilde’s suffering from a slight case of the lollipop heads here but we can’t deny that her yellow and white sundress, strappy sandals and chic updo provide a much needed burst of Spring.
