Everyone has heard of the “ugly Christmas sweater.” You know, the one that’s so hideous you wouldn’t be caught dead wearing it. But the trend has become so popular that people often have parties where the only way you can attend is if you show up in the most disgusting holiday sweater you have. And the uglier the better.

The ugly Christmas sweater first appeared in the 1980s. At that time, it was featured on a situation comedy show. Before long, this tacky sweater was all the rage. Although no one knows for sure, Vancouver, Canada stakes claim to have been the birthplace of the ugly Christmas sweater. Regardless, it’s something that everyone now has but they only pull it out during the holiday season…all for good laughs, of course.

While there are thousands upon thousands of ugly Christmas sweaters, these 35 are probably among the worst.
