Can you buy good jeans? Searching for ethical dress sense for people and planet, model and activist Charli Howard looks on the bright side - and the dark side - of denim.

Charli meets Molly Hopwood, a young designer plucked from Graduate Fashion Week to work for Tu at Sainsbury's. Unlike much of the new generation of ethical jeans, Molly's Denim for Good collection aims to do denim differently, by making it affordable as well as sustainable.

Tansy Hoskins, fashion journalist and author, sheds light on the dark side of denim, from field to factory.
