Suzanne Lee has developed a novel approach to fashion design - she grows her own materials.

The designer came up with the idea when researching a book about how fashion would look in 50 years time.

Using a recipe of green tea, sugar, bacteria and yeast she is able to 'grow' a material which she describes as a kind of "vegetable leather".

She explained her working method to BBC News, at her workshop in south London.
