NEW YORK — Dressbarn, the women’s clothing chain that’s been around for nearly 60 years, is closing all 650 of its stores. The company’s chief financial officer, Steven Taylor, said Dressbarn has not been operating at an “acceptable level of profitability in today’s retail environment.” Its owner, Ascena Retail Group Inc., says it wants to focus on its more profitable brands. Ascena also owns Ann Taylor, Lane Bryant and other clothing stores. The company did not say when Dressbarn will shut all its stores. Dressbarn employs about 6,800 people. Dressbarn has 13 stores in Minnesota, including six in the metro area (Blaine, Burnsville, Coon Rapids, Eagan, Maple Grove and Woodbury). After the news was announced Monday, shares of Ascena Retail Group Inc. rose 2.6 percent to $1.17 in extended trading. Shares of the Mahwah, N.J.-based company are down more than 50 percent so far this year.
