January Jones is just mad for Versace accessories -- wearing clothes, not so much.

The stylish Mad Men actress, 32, poses nude -- accessorized with just a sexy pair of shoes and a well-placed purses -- in the spring/summer 2011 ad campaign for the luxe designer label.

The retro photos were shot in London by Mario Testino -- the famed celebrity photographer whose Prince William/Kate Middleton engagement portraits stormed the web over the weekend.

"I am always on the lookout for the next Versace blonde," Donatella Versace told Women's Wear Daily. "In January I feel I have found a perfect Versace woman for the 21st century...She is chic and elegant but deeply sensual too."
