Game of Thrones star Maisie Williams has teamed up with Dolphin Project, a charity which aims to put an end to dolphin exploitation and torture, and is pictured modelling a limited edition Arya Stark t-shirt on Instagram, which is being sold exclusively for the charity.

Williams said in a statement 'So proud and excited to finally be releasing these tees. I hope you love them as much as I do. Get yours now before they're gone!'. The tops are available for two weeks only.
