An ugly sweater contest is a fun event where participants wear intentionally unattractive or humorous sweaters, often featuring festive designs. These contests are popular during the holiday season, especially around Christmas, and can be held at parties, workplaces, or community gatherings. Judges or attendees typically vote for the most outrageous or creative sweaters, and prizes may be awarded to the winners. The goal is to celebrate the spirit of the season while enjoying laughter and camaraderie among friends, family, or coworkers.
