Celebrated fashion designer Vivienne Westwood passed away peacefully at her home in South London, The Guardian reported late Thursday.

The 81-year-old Dame was behind some of Britain’s more salient countercultural movements, becoming synonymous with the late-70s punk rock scene in London and later playing an outsize role in the early-career development of her muse, Naomi Campbell.

Known as much for her outspoken activism on issues such as nuclear proliferation, civil rights, the environment, and other social justice issues as she was for her clothing line and collaboration with Malcolm McLaren, Westwood’s influence in the broader world of design is hard to overstate.

Zaha Hadid was among the torrent of prominent figures within the UK to have worked with Westwood on collaborations for shoes, flagship boutiques, clothing lines, and even home designs on her way to becoming the “Undisputed Queen of British Fashion.”

“Vivienne and Malcolm use clothes to shock, irritate and provoke a reaction but also to inspire change [...] these attitudes are reflected in the music we make,” musician Viv Albertine recalled in her biography. “It’s OK to not be perfect, to show the workings of your life and your mind in your songs and your clothes.” 

“I will continue with Vivienne in my heart,” Westwood’s husband and creative partner Andreas Kronthaler, told the Guardian finally. “We have been working until the end and she has given me plenty of things to get on with. Thank you darling.”
