Robin Wright has confessed the clothes she wears on House Of Cards leave her exhausted because they are so uncomfortable.

The actress revealed she worked with the wardrobe department and her own personal stylist to design an “armour” for her character, ambitious and scheming First Lady Claire Underwood, but admits it is not easy to wear all day.

Robin said: “What’s tiring is being in the Spanx and the tight dresses – and I’m not kidding.

“You can’t breathe, and the dresses are so tight. I should get a corset, I just thought of that, that would be better.

“And having to stand up so straight all the time, that’s the most exhausting. It’s a physical strain more than anything.”

But Robin admitted she only has herself to blame.

She explained: “The way I work as an actress has always been, my armour comes first. What does this person sit in every day, outside of her birthday suit? That’s who we are. And how does that person move, given that armour? That’s very important. And that helped me understand her more than anything.

“Putting Spanx on, I was like, ‘I can’t imagine wearing these in life!’ But it helped occupy a tenet of woman.”

Robin added: “There seems to be a template design that I find very matronly with the women of politics, in all countries. There’s a look that’s just not sexy. And I wanted to keep her classic, and sexy.

“We’re already getting old, why do you want to look like Grandma?”

But one thing viewers will never see Claire wear is the colour red.

Robin revealed: “We’re not allowed – it’s not part of our template of colour, red.

“It’s a cliche of blood and blah blah blah, so [series producer David] Fincher was like, ‘No red in anything. No red in upholstery, window treatment and especially not wardrobe. No red’.”
