Where did the saying if the glove fits come from?

The saying "if the glove fits, wear it" originates from the courtroom, particularly popularized by the O.J. Simpson trial in the 1990s when Simpson famously tried on a glove that was alleged to belong to the murderer. The phrase means that if something applies to someone, they should accept it. Its roots can be traced back to earlier literature and sayings, often used to suggest that one should take responsibility if a situation accurately describes them. Overall, it emphasizes personal accountability and recognition of one's own actions.
