Halloween's still a week away, but Kourtney Kardashian couldn't wait to get into the holiday spirit, throwing an early bash for her gal pals on Monday, Oct. 24.

The mother-of-three posted a photo of her costume on Snapchat, but all fans could talk about was the 37-year-old's daughter Penelope Disick, 4, dressed as the Bride of Frankenstein!

Although Kourt's sons, Mason, 6, and Reign, 22 months, didn't make cameos at the party, we're sure the fam will eventually pose for another group pic like they did last year.
