Firth impressed with wife's recycled Golden Globes gown

Colin Firth's stylish wife wore the first recycled gown Giorgio Armani has ever made to the Golden Globes on Sunday.

The Oscar winner's eco-warrior wife Livia created the Green Carpet Challenge three years ago in an effort to make the world's biggest fashion houses less wasteful and she debuted her latest initiative - made out of plastic bottles - at the Globes.

She gave top designers like Armani, Tom Ford and Paul Smith the challenge to dress her for the awards season using only recycled materials and vintage couture.

Her first outfit wowed everyone at the Globes on Sunday, including her actor husband.

He says, "It was made of recycled plastic bottles and it feels like silk."

The King's Speech star is incredible proud of his wife's initiative.

He adds, "This is something absolutely extraordinary. It's a completely pioneering exercise. She's launched this all by herself and she now has created an army around her... She challenged herself so that everything she wore would be sustainable."
