My father always wore a hat, except when working, when he wore a baseball cap. I never thought much about it then and I don't spend anytime thinking about it now, either. It was just so natural that you wouldn't have given it a second thought. It wasn't high fashion or anything like that. It was just what some men did. They wore hats. Others rarely did. One of my uncles probably spent his entire life in "work clothes," meaning the matching twill outfits in gray or khaki from the department stores. But I have a photo of him in dress clothes without a jacket and wearing what looks like a straw or Panama hat. The photo was taken in 1943, I think. My wife says her grandfather always wore a suit everyday, even after he had retired. He worked at a boys boarding school in Virginia. He apparently used to wear a straw boater hat in the summer and we have the hat. Unfortunately, it's on the small size and not in good shape, probably from being store in an attic for the last 40 or 50 years.
