Is it even spooky season without a line-up of stellar celeb costumes?

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. And the best part? This year’s festivities are far from over.

As October 31 is still just around the corner, we expect to see more stylishly spooky looks fill our social media feeds in the coming days. We’ll be keeping an extra special eye out for Heidi Klum, the self-proclaimed “Queen of Halloween,” as she teased her “gigantic” upcoming costume on a recent Tonight Show appearance and through an Instagram post.

Until then, here are the best celebrity Halloween costumes of 2023 (so far!).
