Sainsbury’s is aiming to have 90% of its Tu clothing range online by next year.

Sainsbury’s launched a pilot website for Tu last month with an invited group of customers in the Midlands.

Speaking to Sainsbury’s staff magazine The Journal, the retailer’s head of womenswear buying, Anna Clarke, said taking Tu online would allow it to broaden the range, which last week celebrated its 10th anniversary.

“Because there’s a huge opportunity with online, we’ll be able to offer even more choice to our customers - a larger range of sizes, more footwear and accessories, plus specialist ranges such as maternity,” she added.

Clarke said work was also continuing on the brand in-store . “We’ve just started to roll out a new look for Tu in-store, giving it a more contemporary, high-street feel,” Clarke said. “It’s already growing customer spend and frequency of visits. By the end of the year, we’ll have 150 refits. It all helps to contribute to our billion-pound clothing sales target by 2020.”

Last week, Sainsbury’s launched a 10th anniversary collection for Tu, working with TV presenter Louise Redknapp.
