We use recycled polyester wherever we can across all categories including our ready-to-wear collection. Recycled polyester requires less than half the energy to produce compared to virgin polyester, with a 28% reduction in greenhouse emissions.   It takes around 70 billion barrels of oil to produce the polyester and nylon used in fabrics each year, which will take 200 years to decompose.   Re-visit every look from the #StellaWinter26 runway show at stellcmcartney.com #StellaMcCartney
