This is a perfect Ben Zuckerman suit in grey wool. It dates from the early to mid 1950's, and would have been a wonderful 'wear anywhere' suit, at a time when most women wore suits on a daily basis.
The skirt is slightly A-line and is simply designed to allow the jacket to shine.
The jacket is single breasted, and closes with black buttons. the jacket is piped with black trim and the sleeves are cuffed and trimmed in black as well.
The suit was sold at B. Siegel, Detroit. Benjamin Siegel was born in Germany and emigrated to America in 1876. He managed several stores in the south and then moved to Detroit in 1881. In 1904 he opened his own store, selling women's and children's apparel. By the mid 1940's there were seven B. Siegel stores in the Detroit area. In 1981 the last store closed.
