Mad Men star Christina Hendricks says her character’s sex appeal is all down to the authentic Sixties underwear she wears on the TV show.

The 36-year-old actress, who plays Joan Holloway in the drama about a New York ad agency, revealed her on-screen wiggle is due to her stylish wardrobe – including actual undergarments from the era.

‘Everything is incredibly authentic and meticulous,’ she told US chat-show host Conan O’Brien.

‘We have the full undergarments and the slips and the thing over that. It’s a little bit of work to get dressed.’

The curvaceous star added: ‘You put these things on and they make you stand upright and your body naturally moves a certain way.

'I always thought that’s what made this sort of walk happen, although my husband teases me and says I walk like that at home as well.’

Mad Men’s viewing figures plummeted to just 47,000 last week after it was poached from the BBC by Sky.

It is understood Sky is paying 250,000 an episode.

A Sky spokesman said: ‘We will continue to invest in the shows that create more value for our existing customers and give more people a reason to join Sky.’
