The Best Celebrity Halloween Costumes of 2023

Including Heidi Klum's epic red carpet moment that has a cool Canadian connection.

Date November 1, 2023

It’s no secret that celebrities love to go all out for spooky season, and Halloween weekend 2023 was no different. Between the countless stars who got all dressed up to attend the buzziest parties in L.A. to those who shared their meticulously planned looks on social media, the best celebrity Halloween costumes of 2023 did not disappoint.

But while many big names sported looks that lived up to the infamous Halloween hype, this year’s costume planning was a bit more of a challenge for some SAG-AFTRA members.

Due to the ongoing Hollywood strike, the union issued strict guidelines on what members should avoid dressing up as this Halloween, which essentially included all TV or movie characters from major production companies. Instead, the union suggested that members wear more generic costumes, such as ghosts, witches and zombies. So, if you’ve been surprised to see much less Barbie pink from celebs than you expected, you can thank the strike for that.

Although many stars seemingly abided by the rule, it appears that Megan Fox flouted the guideline with her costume. Over the weekend, the actress shared an Instagram post that showcased herself and fiancé Machine Gun Kelly dressed up as characters from the 2003 film, Kill Bill. Not only were the costumes inspired by forbidden film content, but Fox also tagged SAG-AFTRA in the post’s caption, making it clear that her and Kelly’s looks were a protest of the guideline.

Despite the challenges, many other celebrities made the best of the occasion. As always, we were waiting with bated breath for self-proclaimed “Queen of Halloween” Heidi Klum’s costume reveal, which she teased as “gigantic” on a recent Tonight Show appearance and through an Instagram post. Spoiler: It didn’t disappoint.

Until then, here are the best celebrity Halloween costumes of 2023.

Heidi Klum

Heidi Klum outdid herself this spooky season, arriving at her annual star-studded Halloween soiree in NYC dressed as an elaborate peacock. But look a little closer and you realize her enormous feathered tail is actually… people! In a cool Canadian connection, Klum partnered with Cirque du Soleil on the extravagant costume which consisted of more than 650 feet of fabric, printed peacock feathers and Swarovski crystals, and took more than 2,000 hours to create at Cirque du Soleil’s Montreal headquarters, according to a press release. Never one to skimp on details, the elaborate red carpet reveal was choreographed by Cirque du Soleil’s creative director Michel Laprise and incorporated five Cirque du Soleil artists. Oh, Canada!
