For kids, Halloween is a chance to wear an itchy costume and ask your neighbors for candy. For teens and adults, it's an occasion to drink sugary punch and wear something a little too revealing. But for celebrities, it's a chance to spend far too much time and money on a costume, complete with accessories and a hair and makeup look. And despite the horror movie-level nightmare that is the politics right now, this year was no different, as stars like Adele, Kim Kardashian and Jessica Chastain took time out of their busy and fabulous schedules to dress up and honor everything from the ghoulish to the garish. We've got celebs who are in essentially themed ballgowns, celebs as movie characters, celebs who are barely recognizable and celebs who should honestly dress like that all the time (looking at you with that bobbed hair, Kaia). Check out some of our favorite celebrity halloween costumes below:

1. Kaia Gerber in 70s glam.
