Online fashion retailer Asos has seen UK retail sales rise 10% to £205 million in the past five months, taking its pre-tax profit to £44.5m for the year to date.
International sales were also up 64% to £333m and now account for almost two-thirds of retail sales.
Nick Robertson, chief executive, said the positive results were down to improving Asos's product offering and driving business efficiencies.
He also paid tribute to the new "high calibre appointments", including new chairman, Brian McBride - a former UK chief executive of Amazon, who joined in early October 2012.
Kate Bostock, a former top executive at Marks & Spencer, will join the firm in January 2013 as executive director for product and trading.
"We remain positive in our outlook for 2012/13 as we continue our journey to becoming the number one online fashion destination for twenty-somethings, globally," Robertson continued.
"Our International roll out continues and our ambitions for the group are unchanged."
