Kardashian, 34, shared photos Friday on Instagram of her daughter in a furry black-and-white ensemble, writing: "My little stinker is waiting to show daddy her costume. Halloween has started early this morning."
Another photo shows the 16-month-old girl running around her grandmother Kris Jenner's Hidden Hills home seemingly ready to go trick-or-treating. "A skunk is on the loose!!!!" Kardarshian wrote with the image.
Although North has already picked out her Halloween getup, Kardashian appeared to be indecisive over what to wear for this year's festivities, writing on Twitter Thursday that she had multiple outfits to chose from.
"I have 4 costumes this year!!!! Decisions......" the reality TV star wrote.
