Save the Children has announced a collaboration with clothing brand Selfish Mother to celebrate Christmas Jumper Day on December 16.

This year the charity has created a series of slogan sweatshirts modelled by Poppy Delevingne, David Gandy, Jon Kortajarena, Karen Elson, Laura Bailey, Erin O'Connor and Immy Waterhouse. Delevingne commented 'Save the Children is a truly inspiring organisation. Last year I visited the Democratic Republic of Congo and saw first-hand the vital equipment and training that Save the Children is providing to health clinics to help stop children dying from easily preventable causes like malaria and pneumonia. But more needs to be done. And this is why I am working with Save the Children and proud to be supporting their Christmas Jumper Day campaign'.
