arya's white outfit
This outfit has the least amount of pictures available to us. It is impossible to tell if this is a dress, a bodice and skirt like Arya’s other outfits, or pants. From the picture of her riding towards the camera, it looks as if she is wearing leggings. It has some sort of yoke design that looks to be made out of feathers.
Arya also wears a white possibly linen cloak that looks to be floor length. It is hooded and has trim along the edges. She wears a tan arm guard on her right arm and a belt which holds various weapons.
