The survey, based on figures from IMRG, Capgemini and the British Retail Consortium, said shopping in cyberspace had become more popular because consumers were being more cautious about their finances.
As published in the BBC, the report added that the credit crunch and rising inflation had dented internet sales, compared with 2007, however web-based shopping continued to outperform the High Street, said James Roper, chief executive at IMRG.
"Clothes and footwear sales were the biggest losers in physical stores in June, with sales either flat or lower than last year despite heavy and widespread discounting, online, they were the big winners," he said.
The report found internet clothing sales rose 32%, lingerie sales rose 37% and footwear was up 38%. In total, £1.76bn was spent on clothing online in the first six months of 2008, with a record amount spent in March.
Mike Petevinos, head of retail consulting at Capgemini, believes online shops are more resistant to tough trading conditions than bricks-and-mortar stores.
"Convenience and the ability to research and make more informed choices in a time of heightened price sensitivity is a key advantage of the online channel," he said.
