Olivia Wilde's casual-to-catwalk wardrobe

The model-turned-actress has an envy-inducing red carpet and off-duty wardrobe.

 At the LA premiere of The Change Up, Olivia wore a bright red Antonio Berardi dress and Brian Atwood shoes. The nipped-in waist showed off the actress's slim figure.

 Dolce and Gabanna was Olivia's stylish pick for the premiere of her new film Cowboys & Aliens at the 2011 Comic-Con.

 Actress Olivia Wilde jumped on the 'star micro-trend' bandwagon with this printed Dolce & Gabbana dress which she wore to the Los Angeles after-party of her new film The Change Up.

 Giving a masterclass in laid-back cool Wilde paired her flared trousers with a Pink Floyd T-shirt and Alexander Wang sunglasses.

 Olivia was the cover girl of NYLON magazine for August 2011. At the issue's launch party, the model-turned-actress wore an Emporio Armarni jumpsuit.

 While out for lunch in LA the actress, who has starred in hit TV shows including The OC and House, wore her favourite flares with a cross-body satchel.

 Red lipstick spruced up this black and white combo which could have otherwise fallen into the 'boring' bracket.

 Wilde wore a cap sleeve, monochrome Yigal Azrouel dress to the 10th Annual Chrysalis Butterfly Ball earlier this year. She finished off her polished look with a simple Ferragamo clutch.

Simple garments in muted tones is Olivia's trademark off-duty style.
