Traditionally bachelors in Switzerland used a bright red handkerchief to indicate their marital status. The edge of the handkerchief should be visible from the left pocket of their trousers. This is a mark of unmarried men.
It seems like it was much easier to determine whether a man is married or not in the past. Today it’s much more difficult. But still, Swiss women, you are lucky to have such traditions .
