Asda is offering a 100-day money-back guarantee on its bargain-basement £4.50 school uniform.

The supermarket chain has pledged that the uniform, which consists of a polo shirt or Easy Iron shirt, a sweatshirt and Teflon-coated trousers, will last until the end of the Christmas term.

“Over the last two years there has been a gradual acceptance – not at George – of disposable fashion,” said George at Asda managing director Anthony Thompson.

“To contemplate that on children’s wear is a disgrace. It should be made to last.”
