Stella McCartney is making front page news with the announcement that the designer, who abandoned her relationship with Kerring in 2018, has now joined forces with LVMH Moët Hennessy Louis Vuitton, the world’s largest luxury group.

McCartney will remain in her role as her brand’s creative director and also as majority stockholder in the Stella McCartney business. Her additional responsibilities include becoming a special adviser to Bernard Arnault, LVMH’s chairman, and also to the LVMH board, on the topic of sustainability.

The fashion industry has an enormously negative and earth-harming footprint on the environment, and no one in fashion world is better prepared to fill this role of LVMH adviser on sustainability than Stella McCartney.

The addition of Stella McCartney’s voice and brand to the LVMH creative and leadership stable underscores the company’s commitment to gender equity. Since 2017, LVMH has named Maria Grazia Chiuri to head Dior and Claire Waight Keller to lead Givenchy. Arnaut has taken a minority position in the also sustainability-focused Gabriela Hearst, while creating a blockbuster disruption of the entire luxury industry with the creation of a new fashion house Fenty, created with Rihanna.

In talking about her new partnership, Stella McCartney said that since ending her partnership with LVMH rival Kerring, she had been pursued by many potential partners and investors wanting to help expand her business.

In the end, McCartney made a seemingly wise decision, one that gives her an opportunity to have heavy influence on issues that matter to her a great deal, while tapping into funding and a professional contacts base that will give her enormous flexibility. The importance of Stella’s access to Arnault and the LVMH board of directors can’t be understated.

“The chance to realize and accelerate the full potential of the brand alongside Mr. Arnault and as part of the LVMH family, while still holding the majority ownership in the business, was an opportunity that hugely excited me,” she said.

Even iconic products like Prada’s famous nylon bags need to advance to retain their original meaning, relevance, and status. Miuccia Prada is increasingly onboard with sustainability, giving up fur a month ago and now pledging to convert the “virgin nylon’ used in her famous bags to Econyl. a regenerated-nylon yarn that can be recycled an infinite number of times. The new fabric is made from reclaimed ocean plastics, fishing nets and textile fiber waste.

To kickstart the important sustainability effort, Prada will release a belt bag, a tote, duffle, two backpacks, and a shoulder style unisex capsule collection. The project is a collab with Aquafil, an Italian company with more than half a century of expertise in creating synthetic fibers.

A portion of revenues will be donated to UNESCO’s sustainability teaching programs.

When Prada first introduced the now-iconic nylon backpack to the luxury fashion sphere in 1984, it was “really an idea”. “I was searching,” Mrs Prada told Vogue in 2018, “because I hated all the bags that were around. They were so formal, so lady, so traditional, so classic.” British Vogue reminds us of the obvious, that Miuccia Prada’s greatest insight about luxury is that it’s an idea, not a product. Therefore, the product, as well as the brand position, must evolve.
