Kanye West was definitely onto something when he told girlfriend Kim Kardashian that dressing in black and white was the sexiest sartorial option. Although he and Kim have got it wrong a few times (everyone’s human, after all) we hope they will look to Olivia Wilde for inspiration in the future.

Olivia absolutely nailed the all-black trend when she attended Conde Nast Traveler’s “The Visionaries” event in New York last night in a stunning black Alexander McQueen dress. Olivia’s demure but edgy look highlights everything we love about the brand – the structure in the shoulders, the feminine flowing skirt and the sexiness in the plunging neckline.

The actress doesn’t need a fancy belt to accentuate her tiny waist, but the one she chose was certainly a nice touch. It broke up black colour and complemented the golden tones of her hair and make-up beautifully.

Olivia Wilde and Alexander McQueen are a dream team, and we can’t wait for them to join forces again!
