Host an Annual Ugly Sweater Party Who doesn't love a good themed party? Your annual Ugly Sweater Christmas Party will be everyone's favourite when you add a strict dress code of the ugliest sweaters your guests can find. Make it fun by awarding a prize to the ugliest sweater. And if you're not much of a partier, host it on a smaller scale with just your closest friends. Make it a movie night with hot cocoa and junk food! Image Source: Unsplash / Toa Heftiba
