The UK's largest clothing retailer, Marks & Spencer (M&S), is to run a 'wardrobe clear-out' day this week, when customers can take their unwanted clothes to stores.

M&S model Lisa Snowdon is fronting a national advertising campaign for the day.

It follows research by the retailer that found 92% of UK consumers admit clinging onto clothing they never wear. M&S said the average British wardrobe contained an item purchased in 1996, and one in ten had clothes bought in the 1970s.

The event, this Wednesday (8 September), is part of the M&S and Oxfam Clothes Exchange. It is also linked to M&S’ involvement in HRH Prince of Wales’ START campaign, designed to help consumers lead a more sustainable lifestyle, a statement said.

Sir Stuart Rose, chairman of M&S, said: “By doing something as simple as dropping off your unwanted clothes at our stores you can help reduce the 1m tonnes of clothing sent to landfill in the UK each year and generate important funds for Oxfam. Recycling your clothes is certainly the right thing to do environmentally, but it can also help you clear out some clutter and give your wardrobe a new lease of life.”
