Thread, the primary building block for any piece of clothing, is increasingly inspiring a number of fashion labels. At Dior, Maria-Grazia Chiuri experiments with a new tweed made from cashmere, while Indian designer Vaishali Shadangule creates her own fabrics from scratch as part of her homage to the power of nature. And Parisian designer Clara Daguin explores the intersection between science and mysticism through her beguiling use of fibre optic threads.
