This is a fun and nice tradition on Christmas, lots of people wear those Christmas Ugly Sweaters (Which some of them are not that ugly!) but hey! they are called that, and even parties get held to wear your Ugly Sweater!
You can participate in the ugly sweater tradition, if you do not want to wear an Ugly Sweater, you can do an Ugly Sweater Nail Art Design.
Hope you like these ideas. Which one is your favorite?
