In 1896 the Crescent Works, manufacturers of custom-made corsets and "comfortable waists," moved into the upper floors of the new Pratt Block (above). For a few years the corset salesroom was in the central bay on the street between the Portland Café — "Open All Night" — and Hendrick Millinery, one of nine Ann Arbor shops fashioning hats for ladies. By 1909 Schumacher Hardware to the left had expanded into two storefronts of the Pratt Block. They sold everything from bathtubs and sporting goods to toys and vacuum cleaners.
In 1930 Klines Department Store took over the entire Pratt Block. It was the first chain store to challenge local businesses like Mack & Co. with cheaper, mass-produced goods. Next door, Sears Roebuck built a sleek new store in 1940. Until the 1970s Main Street was able to support both chains as well as Goodyear's, the remaining locally owned department store. Sears left downtown in 1974 for the Briarwood shopping mall. Goodyear's closed soon after. Left to itself downtown, Klines expanded into the old Sears space before closing in 1994. By then, most of Main Street's stores had been converted from traditional service and retail businesses to restaurants, specialty shops, and galleries.
