Do you want to build a snowman? Do you also want to let it go (let it gooooooo)? North West is a pint-sized Elsa from Frozen who wants to do both of those things. Although the Disney flick came out in 2013, as many parents know, some tots still have Frozen fever. North West, famous as she may be, is not immune to said fever. Her mother, Kim Kardashian West, just shared a snap of her daughter's most recent Halloween costume on Instagram , and it appears that Nori's love of all thing's Frozen is alive and kicking.
