Halloween costume ideas from stuff you already own

Halloween’s in 10 days and your costume plan is… a vibe?

Raid the closet, then let AI do the brainstorming. ChatGPT, Gemini, Claude, or Grok:

“Give me 6 easy Halloween costume ideas using mostly stuff I already have. Here’s what I’ve got: [clothes, props, colors, random junk]. Budget for extras: $[amount]. Mix funny and clever. For each one, tell me what to add and how long it takes to throw together.”

Costume for a kid? Add their age and what they’re into. Group costume? List everybody.

Quick check: skip anything with open flames, long trailing fabric on little ones, or face paint you haven’t tested on a small patch of skin first.

Worst case you go as “guy who asked AI.” Terrifying.
