Some say 'deshopping' or returning already-worn clothes should be illegal. Others argue it's an invaluable marketing tool — so who's right?

• The fashion sector has to deal with a return rate sometimes as high as 40%.
• Last year, fashion returns created 750,000 tonnes of carbon-dioxide emissions in the UK.
• Research shows some companies value deshoppers and rely on lenient return policies to boost sales.

One shopper, who asked to be called Dani H, said she returns 95% of the clothes she buys online. She's a health and well-being journalist who's done a lot of online shopping lately, but also said it's hard for her to rely on the sizes published on the internet.
