It is illegal to wear pants that expose your underwear in public.

The Law Explained

In a modern attempt to legislate modesty, the city of Columbus cracked down on the fashion trend of sagging pants. The ordinance makes it a misdemeanor to wear trousers or shorts that sag low enough to reveal undergarments or bare skin in a provocative manner. Violators can be slapped with a fine, though civil rights advocates frequently challenge the enforcement of such dress codes.
