SuperGroup, the owner of fashion chain Superdry, has revealed a bumper Christmas, with retail sales surging 93.6% to £51.7m.

In the nine weeks to January 2, total group sales rocketed 90.1% to £65.1m.

Online sales soared 243.3%.

Julian Dunkerton, chief executive of SuperGroup, which also operates the Cult fashion brand, said the retailer is “now positioned to deliver profits towards the upper end of market expectations”.

He added that the retailer has been able to “largely” mitigate the rise in cotton prices “as a result of renegotiations with our suppliers and selected price increases”.

He added: “We anticipate a reduction of no more than 200 basis points to our gross margins in 2012. We will clearly continue our efforts to reduce this impact with our supply base and look forward to the future with confidence.”

Dunkerton said the strong performance “demonstrates the strength of our brand and the loyalty of our customers.  Such excellent Christmas trading figures, coupled with our continued UK roll-out, international expansion and rapidly evolving internet capability, mean that we are now positioned to deliver profits towards the upper end of market expectations”.
