January Jones features in Versace’s new Spring/Summer 2011 advertising campaign which was shot by Mario Testino.

My pick for brand ambassador for Versace would’ve been Blake Lively, but after seeing these subtly sensual pictures I will say that Versace made the perfect choice.

January showcases the new Versace accessories with her sophisticated beauty. It’s so easy to forget she’s naked in these pictures.

Donatella Versace said: “I am always on the lookout for the next Versace blonde… and in January I feel I have found a perfect Versace woman for the twenty-first century. She is chic and elegant but deeply sensual too – it is a ‘dramatic’ combination.”

The black and white photographs and hair and makeup reference the spirit of the Sixties, which is appropriate as January is best known for her role in “Mad Men”.

The advertising campaign will feature bags, shoes, sunglasses and optical frames from the Versace Spring 2011 collection.
