Seems to go way back to the B&W movie era - men in tuxedos, women in evening gowns and boas - glamorous socialites dressed to the nines, watching a couple buys beat each other up. Sometimes the MC is in a tux. I don’t get how that whole package goes together.
Neckties follow similarly.
Fun fact, doctors used to always wear neckties. But it was found that they are great at passing on infections from one patient to another. There was backlash from the necktie wearing doctors when it was suggested they should stop wearing them. Took some time to change.
Bonus: hand washing was also rejected because “doctors are special, they can’t be dirty” (paraphrased)
