Japan’s Fast Retailing Group and denim giants Wrangler and Lee are among the latest six companies to join the Ellen MacArthur Foundation’s Make Fashion Circular initiative.

Originally launched as the Circular Fibres Initiative at the Copenhagen Fashion Summit in 2017, the initiative entered its second phase – Make Fashion Circular – one year later, at the 2018 Summit. Burberry, H&M, Nike, Stella McCartney, and Gap Inc were named as the core partners of the programme, which aims to develop solutions to some of the biggest issues faced by the fashion industry.

Guess, Nordstrom, and pre-owned global fashion platform Vestiaire Collective have also joined the initiative.

Of these new participants, Guess, Lee, and Wrangler are also part of Make Fashion Circular’s Jeans Redesign, which launched in July of last year. Its aim is to help fashion brands and manufacturers transform the way they produce jeans by tackling waste, pollution, and the use of harmful practices.
