(Reuters) - Abercrombie & Fitch Co posted a steeper-than-expected quarterly loss on Thursday, as the apparel retailer had to close stores across the globe due to the COVID-19 pandemic, sending its shares down 8% in premarket trade. The temporary closures of its recently remodeled stores have slowed Abercrombie's efforts to revive its struggling flagship clothing brand, hurt by past fashion missteps. The crisis also hampered growth at Hollister. Net sales fell 34% to $485.4 million..
