Christmas Jumper Day is organised by charity Save the Children to raise money by getting people to - yes you've guessed it - wear a Christmas-themed jumper.

Since launching in 2012, over 17 million people have signed up to take part in the charity event raising 拢16 million.

Lots of famous faces got involved this year too.

After all if it's chilly, you need to wear a jumper so why not a cheesy Christmas themed one!?
