Save the Children ambassador Poppy Delevingne has teamed up with close friend and fashion designer Alexa Chung to create a t-shirt collection, celebrating the 100th anniversary of the charity and its launch of the new Stop the War on Children initiative.

The British model and actress said 'Alexa and I wanted to create something that would help make a change and encourage people to do something good. The future is full of possibility so join us and help make a change for the millions of children that need it the most around the world. Buy our t-shirts and wear them proudly!'.
