Get involved in our cheeky Christmas dress-up day and make a difference to people spending Christmas in hospital.

Taking part is as easy as finding the first door on your advent calendar. Simply dress up as an elf, or in your Christmas fancy dress, with your friends, family, colleagues, classmates or pets and make a donation to your local hospitals.

This is your moment of elf greatness.

Whether youve gone all out from the elf hat on your head to the bells on your elf toes, or youve thrown on your favourite Christmas jumper for the sixth year running, youre all part of something bigger. Youre part of a full-hearted community, looking silly to do something serious. Youre doing great things for people spending Christmas in our hospitals.

Remember to take lots of 'elfies' on the day and share your elf name with us (find out your name below) on social media by using the hashtag #BWElfDay
