Livia Firth in her gorgeous Giorgio Armani gown, which she wore to Sunday’s Golden Globes ceremony

Tom Ford and Stella McCartney are the latest in a long line of fashionable names to sign up for Livia Firth’s Green Carpet Challenge.

The designers have joined a host of other fashion houses, including Chanel, Gucci and Yves Saint Laurent to create eco-friendly dresses for Colin Firth’s wife to wear on the red carpet throughout awards season.

For each awards ceremony (from the Baftas to the Oscars) there will be an actress who will also be wearing one of the ‘green’ gowns.

Livia said of The Challenge; “Over the last three years, The Green Carpet Challenge has become an all consuming passion of mine. This part of the fashion landscape is so exciting because it is genuinely revolutionary and relentlessly positive. It is absolutely the right time to take the challenge up a gear so we are working with our favourite world class designers and actors as GCC ambassadors.”

“Fashion is a brilliant communicator. The fashion we communicate through the GCC promotes social justice, environmental integrity and the very best in design.”

Tom Ford said; “Livia is a close friend and I am thrilled to be working with her on her Green Carpet Challenge, a cause very close to her heart.”

“Sustainable luxury has been at the core of Tom Ford from the onset of the brand, and I am looking forward to creating an iconic red carpet dress that is not only beautifully made, but also ethically made.”

Giorgio Armani launched The Challenge this year, creating the stunning gown that Livia wore to Sunday’s Golden Globes ceremony. He commented; “Livia’s enthusiasm and dedication to this cause has been very inspiring for me. Awareness for the environment is a topic that’s very important for us all: we cannot avoid it.”

The dress was created using fibres from the recycling of households in Northern Italy, and described by Roberta Armani as “created from a special fabric made with fibres derived from the mechanical, non-chemical recycling of plastic bottles”

Paul Smith, Valentino, Roger Vivier and Alberta Ferretti will also creates sustainable, ethical pieces from Livia to wear.

Gucci’s Frida Giannini, who is also taking part said: “Livia’s passion for the mission of this project is infectious.”

“We all have a collective responsibility towards future generations to minimise our impact on the environment and through this initiative we can hopefully show that you don’t have to make any compromises in design and creativity when working with environmentally friendly materials.”
