Vivienne Westwood says how you can spend less, be more engaged and have a really good time. She gives the example of wearing a towel instead of wearing a coat; or putting on your dad’s boxer shorts. Anything which is spontaneous is sexy because “it looks like it could soon come off”. She explains how she uses climate change slogans to pin to her t-shirts. She says, “The more public understand the danger they’re in, the more politicians will start to do something” and accuses politicians of pretending to be green.
