The 39 best celebrity Halloween costumes of all time

For Halloween 2024 Kim Kardashian called in the professionals to create her a scale-fulled alligator costume. In true Kim fashion the business mogul and style muse somehow found a way to show off her impeccable curvy body, sporting prosthetic scales from head-to-toe.

The Jenner sisters aren't ones to skimp on any detail on the best of days and Halloween seems to be no different. One of Kylie's many, many costumes this year was a cosplay of Demi Moore's character Erin Grant in th 1996 Striptease.

Cruella de Vil, but make it runway-ready. Iggy's look was an absolute show-stopper; a monochrome coat, houndstooth pants, and Cruella's signature two-tone hair. Paired with her pet dalmatian, this costume was iconic villain vibes, with just the right amount of fashion-forward attitude.
