Fashion icon Twiggy is calling on customers to get involved in the One Day Wardrobe Clear-out event, launching in 370 Marks & Spencer stores tomorrow.

The retailer is accepting all unwanted clothes and accessories, to be resold by Oxfam in a bid to raise funds and prevent landfill. The event rewards customers who donate with a £5 Marks & Spencer voucher when they spend £35 on fashion in store.
