Livia Firth kicks off her 2012 Green Carpet Challenge at the Golden Globes in Giorgio Armani Livia Firth mobilised her Green Carpet Challenge 2012 at last night's Golden Globes, enlisting the help of fellow Italian Giorgio Armani in her quest to wear only eco-friendly gowns on the red carpet. It's easy being green when your husband is an Oscar-winning actor, your best mate is Laura Bailey, and you have Stella McCartney on speed dial. Easy, but still laudable, when one considers that Livia Firth has world-class designers queuing up to dress her in their hot-off-the-catwalk designs. IN PICTURES: Golden Globes red carpet fashion hits and misses Firth embarked upon something mildly revolutionary for Awards Season two years ago: eschewing this season's designs in favour of dresses that were upcycled, vintage or created using sustainable sources. Sometimes Firth even went one step further in her red carpet rebellion and wore dresses that - wait for it - she had actually worn on a previous occasion. This year Firth has recruited a roll-call of industry veterans to aid her in her eco efforts, procuring the creative talents of everyone from Tom Ford to Karl Lagerfeld. Last night it was the turn of Giorgio Armani to step up to the (ethically-sourced) plate. He opened the proceedings with a black floor-sweeping gown created from a fabric made out of recycled bottles, and also dressed husband Colin in a suave tuxedo.

In a blog-post on Vogue.com, she wrote: "Being Italian, I grew up with Giorgio Armani (figuratively speaking). Indeed during my youth there were only two names that symbolised Italian elegance in fashion: Armani and Valentino. To open the GCC 2012 with a stunning bespoke eco gown by Giorgio Armani - well, that is unreal. It's good to hear that even the wife of Colin Firth gets starstruck; when she met Armani she "couldn't stop hugging the poor man even though I was standing in my underwear for the fitting. He must have thought I was mad, but he bravely continued. Perhaps he's used to that sort of hysteria from women in their underwear!

According to her tweets during the evening, Firth was also wearing vintage Damiani earrings from the 1930s, Roger Vivier shoes 'recycled' from the 2011 Oscars, and an Alberto Parada ring made from conflict-free diamonds. The trailblazing Eco Queen then revealed that she had signed up "THE most amazing actress 4 #Oscars #GreenCarpetChallenge!!!!" Our money's on Meryl Streep.
