Perhaps because their range of fashion choices was so limited, men in the 1950s did not care as much about clothes as women did. As an article in Newsweek in 1957 put it, "men prefer to spend the extra money they're earning on things other than clothes," that is, on their homes and growing families. Probably because of the relative disinterest from men, styles did not change measurably from year to year in the 1950s as they did for women.
