National Ugly Christmas Sweater Day is celebrated on the third Friday of December each year. It is a day of light hearted fun and a day to be yourself and not that buttoned up corporate version of yourself you have grown to despise. Most importantly, National Ugly Christmas Sweater Day is a day to make the holidays fun...the way they were intended to be! So at this National Ugly Christmas Sweater Day, leave the school uniform at home, keep the preppy office blouse in your closet, and whatever you do, don't even think about taking your suit to work. All you need to wear is your ugly Christmas sweater because this is your day, this is our day, and this is National Ugly Christmas Sweater Day!
