💡 Quick Tips for Planning a Group Costume Without Fighting:
- Pick a Monochrome Theme: When in doubt, themes where everyone just picks a different color (like Among Us, Fairies, or Powerpuff) are the easiest to agree on.
- Order 3-4 Weeks Early: Fast-fashion shipping from Shein and Temu takes around 7–14 days in October. Don’t wait until Halloween week!
- Use Basics You Can Rewear: Choose cargo pants, hoodies, and skirts that you can easily integrate into your normal fall/winter wardrobe.
