.... What are you talking about? Bow ties are a notable example of mens formal wear.
They're commonly seen at weddings and the most formal of events like major award events.

Just look at those infantalized... Nobel prize winners, monarchs and national leaders?

Oh, and don't forget that formal naval military attire involves a neckerchief tied quite prominently in a bow much like the underwear.

You put bowties on children because they also snag less, and it's cute when kids wear formal attire.
