Winter 2026 Collection
The Stella McCartney Winter 2026 collection, presented during Paris Fashion Week, reflects Stella’s life and creative journey, celebrating freedom, bold expression, and a deep connection between humans and nature. Honouring the Year of the Horse, the runway experience invited guests into an equine-inspired world exploring themes of strength, movement, and the powerful bond between humans and horses.

BioCir® Flex is a next-generation material that combines high-performance capabilities with environmental responsibility
Compostable & Recyclable
Designed for circularity, BioCir®Flex biodegrades into renewable biomass when composted in industrial facilities or can be recycled for continuous use.
Bio-based Innovation
Made from sustainable sources like castor beans, oils, and polysaccharides, ensuring it does not compete with food resources.
Dyed Naturally
The S-Wave Sport trainers incorporate BioCir®Flex dyed with natural cinnamon, highlighting its non-toxic properties.
Durable & Flexible
As durable as TPU and as flexible as rubber, it absorbs impact and responds to motion, making it ideal for footwear.
“I mean this is insane. My shoe designer came up to me and said, ‘smell the sole’. It’s made of cinnamon waste. It smells of cinnamon! And it's basically 100% plant based, recyclable and biodegradable textile. Its a closed-loop production, so it ensures completely zero waste. It is mindblowing.”
