Halloween costumes being sold by some of the UK's biggest retailers equate to the same amount of plastic as 83 million plastic bottles, a study suggests.
More than 300 items sold by 19 high street retailers, including Tesco, M&S and Aldi, were investigated by environmental charities Hubbub and The Fairyland Trust - of which, 83% of the material used in the costumes was oil-based plastic.
The study estimates that Halloween celebrations will create over 2,000 tonnes of plastic waste from clothing and costumes alone.
Of the 324 items tested, the most common plastic polymer found was polyester, which made up 69% of all materials, while cotton made up just 10%.
Items tested from Aldi, John Lewis and Wilko were made up of 100% polyester.
