15 Trending Halloween Costume Ideas Inspired by TV & Movies

Halloween is right around the corner, and let’s be honest—picking a costume is always harder than it should be.

Bonus: I’ve tried some of these myself, so trust me, these picks aren’t just internet hype.

Why it works: It’s instantly recognizable. All you need is a black dress, white collar, braided pigtails, and that iconic deadpan stare.
