Stella McCartney encourages circular economy with The RealReal partnership

Stella McCartney is doubling down on her commitment to sustainable fashion via her partnership with the luxury consignment brand The RealReal.

The British designer's eponymous fashion empire has renewed its partnership with the sustainable company, which focuses on giving luxury items a second life through resale and avoiding them going to landfill.

Shoppers buying Stella McCartney pieces through the secondhand retailer will be rewarded with $100 in store credit to use at Stella retail stores or online.

"Moving from reducing our negative environmental impact to making a positive impact requires all of us to change our mindset and leverage solutions that will make fashion circular and eliminate waste," said McCartney in a statement. "The partnership with The RealReal created an easy and impactful solution for our customers to participate in a circular economy. We look forward to growing the partnership in 2019."

The RealReal specializes in re-selling genuine, verified luxury items from brands ranging from Gucci to Cartier, and operates in 10 retail locations across the US. But the collaboration with the circular economy-focused brand is not the only way McCartney is making an effort to lessen the environmental impact of her business: earlier this month, she helped launch a 'United Nations fashion industry charter' in Poland that makes the business case for sustainable fashion, and has seen 43 fashion businesses -- including Burberry, Hugo Boss and H&M -- sign up to the initiative.
