New Look saw UK like-for-likes edge up 1.5% in the seven weeks to December 28, with total UK sales nearly double that at 2.9%.
Total sales, including international territories, rose 2.6%.
Ecommerce sales drove much of New Look’s performance, with own site sales up 48% and total sales, including third parties such as Asos, up 62%. Click and collect represented around a quarter of all orders.
Chief executive Anders Kristiansen said: “After a difficult start to the quarter, on account of an unseasonably warm October, trading returned to more normal levels. However, the festive trading window was smaller this year, with customers delaying purchases in order to seek out the best promotions before Christmas.
“In spite of the backdrop of extensive Christmas discounting across the high street, our stronger full price sales performance ensured that we were able to protect our margin - a central component of our strategy - and we also saw our market share grow.
“We are optimistic about the year ahead but remain watchful of the pace of recovery in the UK economy and the continued pressures facing our customers.”
