Online lingerie sales declined by four percent last month, according to an IMRG Sales Index report, which covers the period from September 11 to October 11.
While online lingerie sales fell on the previous month, figures remained up by eight percent on 2010.
Lingerie was the only category, aside from travel (-17 percent), to record a decline.
Across the sectors, online sales increased by seven percent. Womenswear saw a rise of 11 percent on the previous month.
The biggest success stories were health and beauty, with an increase of 44 percent, and alcohol, with a growth of 27 percent.
In contrast to the reported decline in online lingerie sales, shopping.com UK managing director Russ Carrol claimed its sales in the segment had risen by 20 percent over the period.
He said: “Online spending has continued to perform well and we expect this to persist through to the end of 2011 as consumers look online for their Christmas shopping. Once again, clothing has proved a consistently strong category for Shopping.com, increasing by 47% year-on-year and appearing yet again as one of the top items in our monthly barometer of the fastest growing search categories.
“Lingerie and cosmetics also experienced strong growth at 37% and 20% respectively, with shoes also coming in at 20%.”
