Eco warrior? —
British fashion designer Vivienne Westwood has shaved off her trademark fiery red hair -- not for style, but to draw attention to climate change.

Westwood's world —
The 72-year-old 'grandmother of punk fashion' said she also wants to scale back her clothing business, due to concerns over environmental sustainability.

Quality vs quantity —
"I've got too much product," she said at London's annual Women of the World Festival. "I'm trying to completely reduce the scale of operation. I'm concentrating on quality, not quantity."

Political points —
Since helping to forge Britain's punk look in the 1970s, Westwood has become one of the country's most prestigious designers, pictured here with the country's first lady, Samantha Cameron.

Front row seats —
Westwood sports a t-shirt bearing the slogan "Climate Revolution" next to celebrities Salma Hayek, Francois Henri Pinault, Kate Moss and Jamie Hince.

Hair raiser —
In a career spanning four decades, Westwood has become one of the UK's most distinguished designers, receiving an Order of the British Empire from Queen Elizabeth II in 1992. She caused a stir at the time, twirling for photographers without wearing underwear beneath her skirt.

Star power —
Westwood scores front row seats at Berlin Fashion Week alongside "Sex and the City" actress Kim Cattrall. Westwood designed Sarah Jessica Parker's wedding dress in the 2008 film of the series.

Fashion forward —
"Buy less, choose well, make it last," she told the crowd gathered at London's Southbank arts centre. Here she is pictured with husband Andreas Kronthaler at Paris Fashion Week last year.

Punk rock —
Westwood started her first clothes shop with Sex Pistols manager Malcolm McLaren (far left), pictured here with the British punk band in 1976.

Rebel with a cause —
"I think it's not good to just go to a supermarket and come back with bags and bags of cheap t-shirts," said Westwood, pictured here in 1977. "All this consumption is not a real choice."
