For those who don't know much about her, there's a great documentary called "Westwood: Punk, Icon, Activist" from 2018 by Lorna Tucker. Apparently Westwood hated it, but it feels pretty honest. Looks like it's available on Amazon Prime and Disney+ (at least in the UK).
As an anti-consumerist, Westwood gleefully undermined her own business interests. In 2010, she told AAP: “I just tell people, stop buying clothes. Why not protect this gift of life while we have it? I don’t take the attitude that destruction is inevitable. Some of us would like to stop that and help people survive.”
I don’t work at all closely to her life’s focus, or indeed with any significant fraction of her talent and drive, but I’m inspired by her nonetheless. RIP.
