Like-for-like clothing sales dropped last week as the warm weather is thought to have cooled demand for autumn fashion.
The latest BDO High Street Tracker found that fashion sales dropped by 2.67% during the week ending 16 September - however this was against strong comparatives last year when sales rose 15.97%.
In-store fashion like-for-like sales dropped by 7.75%. The report said the warmer weather may have contributed to stagnating sales in-store.
Overall total like-for-like sales fell by 2.73%, but again this was compared to strong growth of 13.35% the year before.
While total in-store like-for-like sales were down by 7.03%, it was a different picture for non-store sales which jumped up by 16.37%.
The report also highlighted that overall footfall dropped by 3%, with shopping centres faring the worst with footfall down by 4.8%. High street footfall declined by 2.6%, while retail parks reported a 2% fall.
