A strong fashion performance helped push John Lewis sales up 2.1% for the week to June 7.
Sales at the business' relocated and expanded Liverpool store, which opened on May 29, were well ahead of expectations, according to the retailer.
Fashion sales were "fantastic", especially kidswear. Nurserywear up 17% and girlswear rose 32%. Fashion as a whole, rose 8%, with labels aimed at a younger customer were up 30%.
Head of supply chain and administration Andy Banks said: "The 2.1% increase was particularly pleasing in the current economic climate. On a two-year basis, the week 19 increase was the third-best improvement of the half, giving real cause for celebration in an increasingly tough market.
He added that the business's stock position was good: "As we prepare for Clearance the operational side of the business is in good shape with availability equal to last year and supply chain lead time improving. We are well set for the run-up to Clearance and our unique combination of value and service will undoubtedly enable us to grow our share of the market."
