The famous supermodel hosted the Yves Saint Laurent Beauté 'Love Your Lips' event to celebrate her role in the brand's upcoming campaign.
Posing outside The Boiler House on Brick Lane, Cara cut an elegant figure in an itsy-bitsy black minidress which was covered in textured fringing.
While we usually spot tomboy Cara in jeans and sneakers, this time she put her impressive pins on full display in sheer tights before adding peep-toe chunky heels.
To give her LBD an androgynous edge the starlet layered a structured blazer by Karl Lagerfeld over the top, piling up her gold necklaces and finishing with sleek locks and a jet black manicure.
On the make-up front the British model opted for her trademark smudgy kohl liner, but mixed things up by lacquering her pout a bold red shade (courtesy of YSL Beauté, no doubt!).
The event was a family affair for Cara, as she was supported on her big night by sisters Poppy (above right) and Chloe (above left).
Poppy oozed effortless cool in skin-tight red jeans, a slouchy grey vest and a Chanel tassel bag, while Chloe warded off the winter chills in a long furry gilet.
Cara has already appeared in campaigns for the high end beauty brand in both 2013 and 2014, and her latest campaign will be released today (21 January).
