Spooky season is here, and out come the Halloween costumes—though we've still got 48 hours to go until the big day, this weekend, fueled in particular by the Casamigos Halloween party on Friday night, already has us assessing which costumes are our favorites. Here's who made the list.

Kourtney Kardashian as sister Kim, circa 2013

Though Kourtney Kardashian is due with her fourth child (a boy, and her first with husband Travis Barker) any day now, she couldn't let Halloween pass by without participating. For the holiday, she brought out an archived piece: younger sister Kim's 2013 (largely panned) look she wore to the Met Gala, while Kim was heavily pregnant with her first child, daughter North.

North West as dad Kanye's "Dropout Bear"

Halloween is a big deal to the Kardashian family, and, speaking of North West, she channeled her dad Kanye's "Dropout Bear" for her costume this year. The bear first appeared on the cover of West's 2004 album The College Dropout; the bear wore the exact outfit North is wearing on the cover of his 2007 album, Graduation.

Kendall Jenner as Marilyn Monroe

Kendall Jenner hosted her own Halloween party this weekend, and the hostess with the most-est turned it out as Marilyn Monroe for the occasion.  Guests at Jenner's party included Billie Eilish, Channing Tatum, and Zoe Kravitz, among others.

We liked these two looks, both from different parts of Britney Spears' 2003 music video for her single "Toxic," so much that we made an entire post about it. (Hilton makes the list again in the "Honorable mentions" section, this time for dressing as another pop icon: Katy Perry.)

Megan Fox and Machine Gun Kelly as characters from "Kill Bill"

Megan Fox and Machine Gun Kelly arrived at the Casamigos party as bloody characters from the Quentin Tarantino film Kill Bill, Fox as schoolgirl assassin Gogo Yubari (complete with blood pouring from her eyes) and Kelly in the yellow jumpsuit famously worn by Uma Thurman.

Name a more iconic couple than Justin and Hailey: the Flintstones? Potentially. After Justin attended the Casamigos party Friday night solo (see above), the Biebers stepped out jointly, dressed as characters from the iconic television show for a party Saturday night.

Lizzo has not been shy about her admiration of the legendary Tina Turner, who died this past May; as a tribute, Lizzo channeled Turner in her Halloween costume, paying homage to Turner in a dazzling manner befitting a fellow superstar.

Somebody had to do it, and it was Kelsea Ballerini who channeled one of the most iconic characters of 2023, Margot Robbie's Barbie from the blockbuster Greta Gerwig film of the same name, for a Halloween party in New York City.
