London Fashion Week: The politics of recycled clothes
We've been to meet designers Vin and Omi, who take an environmental approach to creating clothes.
The designers created their 62-piece collection for London Fashion Week from recycled plastic bottles and 'leather' made from chestnuts.
Vin and Omi say fashion is "wasteful" - and if labels sell to hundreds of stores around the world they "can't possibly be" green and sustainable.
Newsbeat's Hannah Moore went to meet them.
