Cheap clothes have outperformed more expensive garments in durability testing conducted for the discount fashion industry.
The University of Leeds has worked with retailer Primark to test items such as jeans and T-shirts to set "standards" on how long clothing should last.
The university's school of design assessed 65 products, and found a £15 pair of women's jeans to be more durable than their £150 equivalent.
Primark will incorporate the findings of the study into its guidelines and the chain said it hoped the results would help give customers better value for their money.
