It also gave me the opportunity to learn about the UK textile industry and the considerable size, still is today. In 2019 I returned to London, taking a role at Burberry HQ, leading the Raw Materials department in the Menswear & Soft Accessories collection It was here that I had the opportunity to lead the business transformation from conventional to organic cotton, as well as the whole supply chain for the Jersey category, across all divisions.
