Fashion is one of the world’s most polluting industries – more than half of everything we wear is still made from plastic.

In the search for more sustainable ingredients – designers are now turning to those you would normally find on your plate.

Katie Barnfield travels to Sherwood Forest in England to meet Ashley Granter and Aurélie Fontan from Mykko – a company making leather from mycelium, the root system of mushrooms.

Fancy a food based swimsuit? We talk to Dr Kate Riley from Textile Exchange about new developments in so-called bio synthetics.

And in the race to adopt these new materials, could some brands be accused of greenwashing? Rachel Cernansky from Vogue Business takes us through the controversy.

Produced and presented by Katie Barnfield.
