It's that time again. Christmas Jumper Day is officially here!

For the third year running millions of Brits are donning the ugliest festive knits they could find in support of the Save the Children campaign, which is designed to raise funds for the charity's work with disadvantaged children in Britain.

And it looks like a bunch of celebrities including the PM's other half Samantha Cameron and former pop star Myleene Klass also want to "make the world better with a sweater".

As you would expect they have taken to social media to show off their Christmas clobber.

IBTimes UK brings you the best festive knitwear to come out of celebsville.
