Christmas Jumper Day is this year taking place on Thursday, December 7, and once again sees charity Save The Children encourage people to wear festive knitwear to school or work and make a donation.
Since launching the annual event in 2012, it's raised over £30 million to help children around the world.
Ideally for the environment it's best to reuse jumpers bought in previous year or even knit your own.
But if you don't have one and want to take part there are plenty of fun Scottish designs to be found.
Here are 10.
5. One for the Tartan Army
