The 46 best celebrity Halloween costumes of all time

Julia Fox is known for pushing fashion boundaries, and she offered a full explanation with her latest Halloween look, dressed as Jackie Kennedy. She explained on Instagram: "I'm dressed as Jackie Kennedy in the pink suit. Not as a costume, but as a statement. When her husband was assassinated, she refused to change out of her blood-stained clothes, saying, 'I want them to see what they’ve done.' The image of the delicate pink suit splattered with blood is one of the most haunting juxtapositions in modern history. Beauty and horror. Poise and devastation. Her decision not to change clothes, even after being encouraged to, was an act of extraordinary bravery. It was performance, protest, and mourning all at once. A woman weaponizing image and grace to expose brutality. It's about trauma, power, and how femininity itself is a form of resistance. Long live Jackie O."

In 2025 the queen of Halloween struck again. For her annual bash, Heidi Klum wore a dramatic Medusa costume complete with moving snakes on her head and a super creepy tongue.

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.

Snow White got a major glam-up in this Halloween look Demi Lovato wore in 2023. With a fitted bodice and deep neckline, this costume was given a sultry edge while keeping the fairy tale magic alive. The perfect balance of classic Disney princess and modern day bombshell.
