The Du-Rite dress company was one of the more prolific Canadian ready-to-wear fashion manufacturers of the 1950s and 1960s.
Max Gladstone was born in 1899 and immigrated to Canada in 1926. His future wife, Tillie Cohen, worked in a dress factory and it was she who taught Max how to sew. The couple soon owned a dress shop on College Street, sewing custom orders in the back room. When the Canadian clothing industry expanded after World War II, especially in Toronto, Max and his brother-in-law Joe Cohen founded the Du-Rite dress factory. Stylish, affordable LBD’s (Little Black Dresses) and dressy daywear were the specialty of Du-Rite.
I have not found a date for when the company opened, but Max’s grandson Jonathan Gladstone, recalls they closed their business in about 1972 (see comment below).
