Alexa Chung and Anna Wintour were just a couple of the stylish fans spotted at Stella McCartney's Fall '19 show in Paris' opulent Palais Garnier – dedicated to the label's #ThereSheGrows conservation project, the collection is a "love-filled celebration of strength and sustainability" and includes pieces you'll want to keep forever. Unveiled on the runway, these boots are made from stretchy vegetarian patent-leather for a sock-like fit around the ankle and set on a chunky rubber platform.
