The spooky season is upon us and Halloween costumes are out. There are still 48 hours until the big day, but we are already evaluating which costumes are our favorites from this past weekend, especially in the wake of the Friday night Casamigos Halloween party. Here is the list.

Kourtney Kardashian is about to give birth to her fourth child (a boy, her first with husband Travis Barker), but she can't afford not to attend Halloween. This is the look her sister Kim wore to the Met Gala in 2013, when Kim was pregnant with their first child, daughter North.

Halloween is a big event for the Kardashian family, and speaking of North West, his costume this year was his father Kanye's "Dropout Bear". The bear first appeared on the cover of West's 2004 album The College Dropout, and was dressed in the exact same outfit that North wore on the cover of her 2007 album Graduation.

Kendall Jenner hosted her own Halloween party this weekend, and the most gorgeous hostess was transformed into Marilyn Monroe for the occasion. Guests at Jenner's party included Billie Eilish, Channing Tatum, and Zoe Kravitz.

We liked these two looks so much in the music video for Britney Spears' 2003 single "Toxic" that we wrote one article about them. (Hilton is listed again in the "Honorable mentions" section: Katy Perry.) [Megan Fox and Machine Gun Kelly dressed as bloody characters from Quentin Tarantino's film "Kill Bill" at the Casamigos party. . Foxx dressed as high school girl assassin Gogo Yubari (bleeding from the eyes), while Kelly was dressed in a yellow jumpsuit famously worn by Uma Thurman.

The Bieber's conquered Halloween this weekend without sharing, with Justin donning a pink and orange Hawaiian shirt with a snorkel and foot fins for the Casamigos party, and Haley doing a 180 and Rachel Green from "Friends" in two vampire and look on Instagram.

Name a couple more iconic than Justin and Haley: the potential of the Flintstones. After Justin attended the Casamigos party solo on Friday night (see above), the Biebers went out jointly for Saturday night's party, dressed as characters from the iconic TV show.

Rizzo was not shy about sharing his admiration for the legendary Tina Turner, who passed away in May of this year. As a tribute, Rizzo channeled Turner in a Halloween costume, paying tribute to Turner in a dazzling manner befitting a fellow superstar.

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