It's not even Oct. 31 and North West has already sported not one, but two different Halloween [1] costumes! Last week the 2-year-old dressed up as a unicorn [2] alongside her aunt, Kourtney Kardashian, and cousins, Mason, Penelope, and Reign, who were all in superhero outfits. On Thursday, North was back in a special costume — this time as Elsa from Disney's Frozen — with Penelope as Anna. Though we've yet to see Kim Kardashian [3] get into the Halloween spirit, she's been all about the spooky holiday in years past. See Kim's sexiest costumes [4] over the years and then look back at North's Halloween look from 2014 [5].
