If you can have the best and funniest Christmas jumper around your office then you've officially won at festivities. Christmas jumpers bring some more fun to the festive season, and make it a competition between friends, family, colleagues - so long as it's friendly competition! We do love seeing the photos come Christmas time of a family fully kitted out in funny Christmas jumpers. We've even seen a photo with a pet tortoise in a little knitted number. This year, take your Christmas jumper to the next level with a Digital Dudz jumper - scroll below to see how these work.
