I was watching an episode of "What's My Line" on Game Show Network from, I think, 1959. One of the contestants was a woman about 40 years old, who was very attractive, wearing a tight cocktail dress and diamond earrings. She was from Ontario, Canada and was self-employed. The panel failed at guessing her occupation.
She was a baseball and softball umpire and worked Canadian amateur baseball and softball. The panelists said she "certainly didn't look the part".
I don't think she wore that dress and earrings while working, though.
