If this has been discussed before, I apologize. I searched but wasn't able to find anything. It is my understanding that men and women in the U.S. stopped wearing hats every day in the 1950s. Does anyone know if this is correct? Also, does anyone know to what the decline in hat wearing is attributed? I believe it to be both the popularity of the automobile, as well as a general rise in casualness in clothing. The reason I point to the car is that the rise in auto travel was about the same time, and it's just not convenient to wear hats in cars, other than baseball caps. As the headrest went up and the roof went down, it just wasn't practical to wear brims or anything of height. Does anyone have any information on the decline of the hat?
