The volume of sales in clothing and footwear stores increased by 1.7% year on year in July, as the warmer weather encouraged shoppers to spend.
The amount of money spent in clothing and footwear stores rose 0.6% in the four weeks to 30 July, compared to the same period last year, data from the Office for National Statistics shows.
However, average store prices in this sector fell 1.1%.
Overall, the volume of sales grew by 5.9% year on year across all retail sectors, while the amount of money spent increased by 3.6%.
Average store prices across all sectors, including petrol stations, fell by 2%.
The amount spent online jumped by 16.7% year on year.
The ONS said: ”Annual growth in retail sales strengthened in July 2016, continuing the trend seen in the last few years. This was mainly driven by department stores but also clothing, which may have been influenced by unusually warm weather in July.”
