Falling on the third Friday of December, which this year happens to be December 15th, is National Ugly Christmas Sweater Day! Celebrating this holiday is as simple as it sounds. Buy an ugly Christmas sweater and wear it.

Although, if you want to be a pro, it's customary to look as crazy as possible on this silly winter holiday. Some good tips on how to amplify your ugly look are as follows:

  • Pick the most ridiculous graphic you can find such as wacky animals, cartoon characters, or Christmas characters.
  • Make your look glow, literally. Buy a sweater rigged with lights or accessories that glow in the dark.
  • Clash, clash, clash! Pick traditional holiday colors and then make them clash with other non-traditional colors like neon pink!
  • Decorate your own. If you decorate your own, you can make it as wild as you want!
  • Go vintage. Get an old ugly Christmas sweater from the 80's and rock it out.
  • Use pop culture. Do the most outlandish spin on something trendy.
  • This is probably one of the best national holidays around. Who doesn't love dressing up in something that lights up and makes someone laugh? 'Tis the season! So spread some cheer by wearing an ugly Christmas sweater this year!
