ROCHESTER, Minn. — The premier clothier for men’s suits in Rochester for 87 years, Hanny’s in the downtown pedestrian subway, is closing its doors. Business attire in once button-down down Rochester has shifted. Incrementally the city’s coat-and-tie regimen has faded. Hanny’s owner, Tim Berg, noted that overhead was outpacing sales. Berg hopes to liquidate his inventory with heavy discounts by the end of July.
