Total sales grew 2.3 per cent during the 13 weeks to the end of June despite being impacted by the introduction of a new website, the company said in a trading update.
"We have seen a continued improvement in clothing, although as anticipated the settling in of the new M&S.Com site has had an impact on sales," said the retailer's chief executive Marc Bolland.
"We are pleased that the womenswear business was in growth, driven by full price sales," he added in a statement.
Problems remain however across the group. Aside from online sales sliding 8.1 per cent because of teething problems linked to the new M&S website, the company reported a 0.6-percent drop in overall clothing sales.
On the upside, food sales grew 1.7 per cent in the quarter.
"Despite some improvement in consumer confidence, market conditions remain challenging," M&S said, adding however that it was maintaining its full-year guidance regarding group performance.
