I know. My father was one of them. The only time I saw him in dungarees was when he was doing yard work or working on his car. Even on weekends, he would wear dress slacks, wingtips, and a button down shirt. When he passed away, he had a closet full of ties, many of them dating back to the 1950s and 1960s.
Never saw him even in a pair of shorts. He used to give me such a hard time for wearing them! Said they were for little boys.
I KNOW!! When my dad died, he had 12 DOZEN SILK BOW TIES UNUSED, so everyone that came to the funeral GOT and WORE ONE OF HIS BOW TIES!! BABIES et al!! IT WAS ADORABLE!!
