Sansa (and Catelyn) have high cheekbones and thick auburn hair.
Arya is “skinny” and looks like Ned, with “lusterless brown” hair and a “long and solemn” face (also attributed here to Jon). (Sansa, Bran and Rickon are described in contrast as having “easy smiles.”)
And Arya is called good at managing a household; do we ever hear about that again?
Bonus direwolf description: Nymeria has yellow eyes; Ghost is larger than the other direwolves.
