Warm & Wonderful is a British luxury knitwear brand founded by friends Joanna Osborne and Sally Muir, who began selling their knitted jumpers out of a market stall in West London’s Covent Garden in 1979. Their flagship design — one black sheep amongst a flock of white ones — instantly became a global phenomenon when a young Lady Diana Spencer was photographed wearing it to a polo match in 1981. Beloved by individualists around the world, the popularity of the iconic “Black Sheep” design still endures today: it’s been enshrined in Britain’s Victoria & Albert Museum, and, in 2023, Diana’s original jumper was sold at auction by Sotheby’s for over $1.1 million USD. “After so many years,” say Sally and Joanna, “it’s lovely to see that this simple design is making people smile.”
