H&M has united with UNICEF on a joint project where 25% of the sales from the All for Children Collection, plus donations from H&M, will go to help children in some of the poorest areas of the world. Below is a video showing the collection, that includes costume pieces that would be perfect for a Fancy Halloween. The clothing is available in all H&M stores that carry kids clothing. 

The video below introduces you to the children who are now in school thanks to the All for Children project.
