Asos is expected to announce a 35% rise in sales over the Christmas period, as shoppers stocked up on festive knits and party dresses.
Turnover at the e-tail giant is forecast to have increased to £335m between September and December, compared with £249m last time, according to The Sunday Times.
A trading update will be released from the company on Tuesday (January 14).
In November Asos launched its much-anticipated Chinese site Asos.com/cn, taking the etail giant to its eighth territory.
Asos now attracts more than 21.3 million unique visitors a month, with 13.2million registered users and 7.1million active customers.
