Swedish clothing chain Lindex AB on Monday posted an 8.3 per cent climb in nine month sales to 408 million euros from the year-ago period as it was boosted by the acquisition of fashion retailer Twilfit. The operator of nearly 350 stores in Sweden, Norway, Finland and Germany said same-store sales climbed 1.3 per cent and improvements to its supply chain boosted its gross margin to 55.7 per cent from 50.2 per cent.
