Clothing sales have taken the hardest hit as online retail sales growth for the month of September slumped to its lowest since 2014.
With an increase of 2.2% year on year, the clothing sector performed significantly below the five-year September average increase of 7.4%, the latest IMRG Capgemini e-Retailer Sales Index shows.
Overall online retail sales experienced their lowest September growth since 2014, at 7.5%.
In comparison, online retail sales growth was up 10.1% in the third quarter, and 17.1% in the second.
Despite a brief uplift around the August bank holiday, sales have faltered since the close of the hot summer.
Sales via smartphones, however, increased 16.1% on September last year.
Strategy and insight director at IMRG Andy Mulchahy said: “The strong second quarter, stimulated by events such as the royal wedding, World Cup, and heatwave, may have left people with less disposable income in quarter three.
“Shopper confidence appears to have fallen at a time when numerous retailers are putting out profit warnings and announcing store closures.”
