What to wear: There are plenty of direwolves to choose from, so this is a great opportunity to grab a few friends so you can be each of the Stark children's loyal, furry companions. Throw on a pair of wolf ears and attach a furry tail to the back of your pants. If you're going as Ghost (Ghost + Jon Snow = adorable couples costume), make sure you keep everything in shades of white.
How to act: Loyal to a fault. It's finally time to show off your animal side!
