Stella McCartney introduces plant‑based “fevvers” (feathers) for Spring/Summer 2026

At her Paris show, Stella McCartney debuted “fevvers” — bird‑free, plant‑based feather alternatives — as part of a collection reportedly 98 % eco‑friendly.

The move aligns with her longer‑standing stance against animal skins and fur in fashion, and demonstrates how luxury brands can redefine materiality. These new biomaterials (including mycelium leathers, plant‑based textiles) suggest the luxury segment is no longer lagging in sustainability innovation. The challenge remains in scaling cost‑effectively, but the creative signal is strong: luxury and craft can lead circular and cruelty‑free design.
