LEG UP: Luxury hosiery maker Wolford AG on Thursday reported a 10.5 percent increase in fourth-quarter sales, to 28.5 million euros, or $34.3 million. Dollar figures are at the average exchange rate. For the fiscal year ended April 30, sales increased 4.4 percent, to 121.4 million euros, or $150 million. “There is no reason for exaggerated euphoria, but with four quarters of sales growth in succession, it’s fair to call this a turnaround,” Holger Dahmen, the firm’s chief executive officer, said in a statement. Wolford said that broadening its product portfolio, a more fashionable offering, new advertising campaigns, a store redesign and openings in Brergamo, Kassel, Milan and Beverly Hills helped bolster sales. By product group, sales in legwear, the firm’s core business, rose 2 percent in the year, but were topped by the firm’s bodywear sales, which rose 9 percent. Wolford also named Antonio Berardi its creative director, confirming a WWD report.
