Model Lily Cole kicked off Vivienne Westwood's Red Label show at London Fashion Week with a modern dance.
Westwood said the solo performance was a metaphor for their climate change concerns; a theme which ran through the show.
Westwood said: "I just use fashion as an excuse to talk about politics. Because I'm a fashion designer, it gives me a voice, which is really good."
The show closed with an appeal to the audience to fill in a climate change postcard to send to the UN Secretary General Ban-Ki-moon.
