LOOK OF THE WEEK

Rooney Mara

Crime scene - Dubai Film Festival

Folks, in decades to come we'll all be ooh-ing and aah-ing at a museum over this amazing ruffled gown by Lanvin. The petite actor does justice to this custom made and utterly glorious gown by keeping the rest of her look simple. 10/10

Nina Dobrev

Crime scene - TrevorLIVE LA

Sexy Vampire is super cute in this blue Elie Saab floor-sweeping gown with lace bodice and adorable button-down collar. Wasn't so adorable when she turned up later that night in a fast-food restaurant without her shoes and ordering a burger and fries. 8/10

Duchess of Cambridge

Crime scene - Mandela: Long Walk to Freedom screening

Euro queen of chic loves to mix it up - and why not when she does it so well. Here a winter white long-sleeved Roland Mouret gown cinched at the waist and with a sexy side split worn with black Prada pumps and a Zara statement necklace. 9/10

Kate Middleton, Duchess of Cambridge.

Jennifer Lopez

Crime scene - March of Dimes luncheon

With her toned bod and teeny-tiny waist, a cinched strapless dress will always be the A-game choice for singing actor and yummy mummy. Adore the bold floral print too. 9/10
