Looks of the Week - 14/04/12

The weekly round-up of celebrity style

Posed with Poise

Dutch model Doutzen Kroes brings back the monotone pants suit, dressed up in a royal purple ensemble by Rachel Roy. The cut-out tunic is clinched in with a wide black waistband.

Jessica Alba shows us that a little black dress needn't be bland and predictable. She added a spark of panache to her tiered Giambattista Valli frock with a pair of yellow, white and black Prismick sandals by Roger Vivier.

Emily Blunt was polished in a navy blue and black horizontally striped Carolina Herrera dress with sheer hem and half sleeves. Black Louboutin peep-toes complete her look.

Reality star Audrina Patridge faultlessly mixes red with pink, wearing a slender fit and long-sleeved Thatcher mini, brightly accompanied by neon pink Jimmy Choo shoes and an oversized magenta Phlox clutch.

Emma Roberts uses a glittery black Joe's Jean jacket to liven up a simple white tee and black trousers. Brian Atwood pumps fit her feet.

Street Chic

Jessica Alba does not fail to impress with her chic street style yet again. She casually slings a black blazer over a floral dress, black tights and worn out boots, upping the cool factor with a black fedora and Tory Burch sunglasses.

Kate Bosworth isn't afraid to experiment with different styles. She pairs a grey gym sweater with a wispy mint green pleated skirt and a silver JewelMint bag. She added a sporty element with suede high tops by Isabel Marant that stand out with their colourful straps.

Alexa Chung covers up in a classy navy blue duffle coat with large pockets, worn over a collared dress, tights and flat brown moccasins. 

Kristin Cavallari's breezy Spring style includes a floaty white maxi dress, accented with a leopard print belt, and worn under a light wash cropped denim Levi's jacket. She carries a tan Foley & Corinna sling bag and strides in Havaianas.

Evening Elegance

Victoria's Secret model Erin Heatherton donned a yellow chiffon Carolina Hererra spaghetti strap gown with interestingly embroidered grey and black printed inserts.

Lake Bell is my favourite 'look of the week'. The brunette actress was gorgeous in a mint green chiffon Marchesa gown with gold embellished detailing on the strapless bodice.

We've seen Brooklyn Decker's style develop over the past few weeks. On this occasion, the 'Battleship' actress opted for a more edgy evening gown, by J.Mendel. It features a fitted black mermaid skirt, black and white triangular cut-out bodice and dissonant shiny gold sleeves.

Coco Rocha looked fit for a fairy tale in a spectacular apple mint Zac Posen gown, with sheer winged cap sleeves and a beautifully embroidered tulle train.
