Channing Tatum & Zoë Kravitz
Channing Tatum and Zoë Kravitz went in a creepier direction with their couple’s costume at Kendall Jenner’s event: The duo became key characters from Roman Polanksi’s 1968 thriller Rosemary’s Baby.

The singer looked sleek as ever at Bette Midler’s Hulaween event, where she wore a body-hugging latex Catwoman costume. Bailey shared some closer looks at her superhero style on Instagram, writing, “i’m dangerous baby 🐈⬛🐾.”
The former Top Chef host perfectly fit this year’s Hulaween theme, Once Upon a Hulaween: Scarytales & Deadtime Stories. Lakshmi’s costume simultaneously captured Little Red Riding Hood’s crimson cape style and that of the Big Bad Wolf, with fuzzy ears and face makeup.
Lakshmi’s mini-me Krishna came along as well, wearing a goth-style gingham getup. The mother-daughter duo was joined by Awkwafina, who turned up in a flame-patterned t-shirt and sunglasses as Guy Fieri.

While stepping into hostess mode at a Halloween bash with The Original Donut Shop in New York City, Kelsea Ballerini rocked a hot pink cowgirl Barbie costume inspired by Margot Robbie’s look in the film.
When searching for a baby bump-friendly Halloween costume this year, Kourtney Kardashian looked no further than her own family. The Lemme founder — who is expecting her fourth child — stepped into sister Kim Kardashian’s 2013 Met Gala look, which she wore while pregnant with North West.
Kourtney shared a series of photos to Instagram wearing the full-length floral gown — with her hair and makeup styled to emulate her little sister’s — along with the caption “Freaky Friday.”
For Keke Palmer’s first Halloween as a mom, it’s no surprise she incorporated eight-month-old Leodis “Leo” Andrellton into her look.
