Pre-loved style pioneer Bay Garnett’s just-published book Style and Substance: Why what we wear matters is an eclectic celebration of clothes and self-expression, with pieces from contributors including Rachel Weisz, Zadie Smith, David Bowie, Joan Didion and M.I.A. Garnett has over two decades’ worth of experience in the fashion industry and is credited with being the first person to do a fashion shoot entirely with second-hand clothes for Vogue in 2003. She will be in conversation with the celebrated costume designer Sandy Powell, three-time Academy Award winner for Best Costume Design (with 15 nominations) who received the prestigious BAFTA Fellowship earlier this year, the highest honour the Academy can bestow. Sandy modelled a second-hand 1960s purple Dior suit in London Fashion Week’s opening show, which was curated by Bay Garnett using clothes from Oxfam’s warehouse. The two will be discussing how dressing can affect how you feel and how others feel about you, and their shared joy in thrift shopping – the delight of discovery and the pleasure in curating outfits that are utterly unique. A book signing of Bay’s book Style and Substance: Why what we wear matters will follow this event.
