Stella McCartney at PFW

Stella McCartney staged her Fall/Winter 2026 runway on March 4, 2026 (wwd.com). The presentation took place inside the riding hall of the Société Équestre de Paris — billed in coverage as Le Grand Manège Jean Caucanas (lesfacons.com). The opening sequence featured live horses: the Associated Press reported ten horses (five black, five white) leading the show (apnews.com). WWD and other outlets described a slightly larger cavalry of a dozen equines and credited horse artist Jean‑François Pignon with the choreography (wwd.com). The brand’s press materials list the ready‑to‑wear lineup as crafted from 93% sustainable materials and entirely free from animal leather, feathers, fur and skins (stellamccartney.com). WWD highlighted specific production details including 100% recycled denim, non‑plastic sequins and lead‑free crystals used across the collection (wwd.com). McCartney’s statement and the press pack name Brewed Protein™ as a vegan wool alternative included in the season’s knitwear (stellamccartney.com), and Spiber — the Brewed Protein™ developer — confirmed the fiber used measures about 12–14 microns in diameter for Winter 2026 pieces (spiber.inc). The official materials also list grape‑based VEGEA for leather alternatives, Airlite® air‑purifying bags, Living Ink algae pigments and RCO100™ recycled cotton among the innovation roster for the collection (stellamccartney.com). Front‑row guests called out by WWD included Sir Paul McCartney, Oprah Winfrey, Gayle King, Isla Fisher and Machine Gun Kelly, underscoring the show’s high‑profile pull (wwd.com). Several outlets framed the runway as a 25‑year milestone for the Stella McCartney label, tying the equestrian spectacle to a quarter‑century of the brand’s cruelty‑free stance (fashionotography.com).
