Fashion designer Stella McCartney said she hopes to set an example for sustainable practice in the industry as she was made a CBE at Windsor Castle.

The 51-year-old has championed a vegan lifestyle and sustainable design since the beginning of her career and recently launched her brand’s first regenerative cotton garments.

McCartney, who received her honour from the King on Tuesday, told the PA news agency she aimed to “set an example for sustainable practice”, including using mushroom leather to create her handbag.

She said: “The majority of the fashion industry is making handbags and shoes out of animals, and very unsustainable sourcing, manufacturing and distribution.”

The designer, who was honoured for services to fashion and sustainability, added: “I feel very privileged to be in the position as a founder of the British fashion house that I can be mindful and conscious in the decisions I make.

“If I can do it, anyone can do it. We need to get more fashion houses and fast fashion working in this way, because every single second there’s a truckload of fast fashion burnt or buried – it’s a dirty business.”

McCartney was recognised in the late Queen’s 2022 birthday honours and said accepting her CBE from Charles was “the greatest moment” of her professional life.

“I feel very lucky and I feel really proud to be British. I’m half-American but my business is here, my home is here, and it’s moments like this that I feel it’s great to be British.”

McCartney has enjoyed a myriad of achievements in almost three decades in the fashion industry, including designing Meghan Markle’s wedding reception dress, and the Team GB Olympic kits in 2012 and 2016.

“Working on the 2012 Olympic Games was an absolute highlight of my career. That was a mind-blowing and memorable experience, it makes me emotional to think about it, I was so proud to be part of it,” she said.
