One of the best parts of Halloween is putting together a fun and creative costume, and celebrities are doing just that as they celebrate the spooky holiday this year. Ahead of Oct. 31, stars have been giving glimpses of their looks on social media and on the red carpet. Hayley Kiyoko completely nailed her Squid Game costume, while Jamie Lee Curtis perfectly channeled her mother Janet Leigh’s character in Psycho for the Halloween Kills premiere earlier this month. A handful of stars with October birthdays like Doja Cat and Drake have also been hosting Halloween-themed bashes. See more pictures of celebrity Halloween costumes ahead.
