Her first one, which she wore on Friday night, was a snow princess, which totally reminded us of "Frostbyte" from Taylor Swift's "Bad Blood" video.
On Saturday night, Kylie was hosting a Halloween party at Bootsy Bellows in West Hollywood and she showed up dressed as a super sexy warrior princess. Apparently it took 40 inches of hair to pull off the look, but it was definitely worth it!
The rest of Kylie's crew were dressed as ninjas, which was apparently Ky's idea.
Kendall Jenner was there, too, but she went with her own, supermodel-style theme, dressing as "Lady Karl," a female version of famed fashion designer, Karl Lagerfield.
As for the rest of the Kardashian crew, they celebrated back at home in Calabasas, with Kourtney Kardashian and her kids dressed as superheroes and Kim Kardashian dressing as herself from the 2013 MET Gala.
Happy Halloween, Kards!
