Spanish fashion designer and retailer Adolfo Dominguez on Wednesday posted a 20 per cent year-on-year jump in first quarter net profit to 2.2 million euros on higher sales and larger store base. But the operator of around 230 stores said although revenues climbed nine per cent to 38.2 million euros from the year prior, same-store sales I the 12 weeks to March 31 fell by an undisclosed amount.
