This wonderful Ben Zuckerman suit, which dates from 1958, is a delight! Made of purple houndstooth wool, and trimmed with beaver at the cuff and collar, it has a peplum jacket and a straight skirt. The jacket is belted at the waist, which draws the eyes to the slim middle section.
This suit was sold at Levine & Smith, New York, which was a ladies' wear store founded in 1948.  The store no longer exists.
