Whether you're at work, school, shopping or home dress up in festive knits, the sillier the better, and let's raise money for Save the Children.
Everyone can get involved and we want to see your #christmasjumperselfie.
This year, a whole host of celebrities are co-knitted to Christmas Jumper Day. James Corden, Jack Whitehall, Fleur East, Myleene Klass, Jess Wright, Jon Snow, Freddie Flintoff, Jamie Redknapp, Claire Richards, Ashley Jensen, Conor Maynard, Sophie Ellis Bextor, Wretch 32 and Rylan Clark have all popped on a pullover to mark their support for the campaign.
