Fashion sales at John Lewis increased 5.2% for the week to December 14, driven by own-brand womenswear label Kin and childrenswear.
Kin posted a 31% increase week on week, while childrenswear sales were up 14%.
The department store reported that overall sales were up 0.6% to £150.7m compared to last year, although the figure was a 5.8% decline on the previous week.
Online sales were up 10% on 2013 and click-and-collect orders were up 32%. Sales in shops made on tablets or at kiosks increased 31%.
The retailer said it “stood up to the challenge” of changing shopping habits, pointing to the demand from Black Friday which resulted in an “unprecedented peak in customer orders”.
Andrew Murphy, retail director at John Lewis, said: “This is the time of year when all aspects of retailers’ operations are put to the test, and I’m very proud of how John Lewis Partners in our shops, distribution network and contact centres, have risen to the challenge and continued to deliver fantastic levels of service at their busiest time of year.
“It’s been a solid week of trade, and our results through the whole pre-Christmas period are encouraging. With fewer than 10 days to go until Christmas, it’s still all to play for.”
