For her appearance on The David Letterman Show this summer, Brittany obviously decided to go the sophisticated, ultra-glam route.
She's kept her look simple and opted for an elegant black lace cocktail dress, teamed with suede platform peep-toes. And the lack of jewellery lets her outfit speak for itself.
Get glam and head to Warehouse, where you'll find this practically identical version, £85, 6-16, then stop in at Office and grab these platform heels for £49.99, 4-8.
