Plan a themed party people can actually costume for

Plan a themed party.

Occasion: [details]
Boldness: [subtle / full costume]
Kids: [yes/no]
Budget feel for decor: [rough]
Allergies: [list]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Three theme options with easy costume paths.
2. Food/decor ideas for the pick.
3. Invite wording for the dress code.
4. A last-minute costume backup.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, prices, opening hours or bookings. UK English.
