Prompt
Create a Halloween costume theme for this group. Participants and preferences: three adults: one likes stars, one likes books, one prefers minimal accessories Constraints: use existing clothes; avoid complicated props Use only the details I supply. Ask for essential missing information rather than inventing it. Label suggestions as ideas, not facts or confirmed bookings. Do not invent prices, people, schedules or offers. Give 3 original theme choices. Each participant gets a distinct role, reusable wardrobe pieces and a low-effort alternative. Include a no-costume role so participation is optional. Do not infer ages or sizes not provided, use full-face masks, or propose working weapons. Pick a theme only after comparing preparation burden across the group. Include a short group-photo arrangement that does not obscure faces.
Customise
For example: three adults: one likes stars, one likes books, one prefers minimal accessories.
For example: use existing clothes; avoid complicated props.
Fields start with illustrative values; replace them with your own facts. The prompt updates as you type. Copy prompt copies your version.
Example output
Actual tested output. The notes used for this result are an example, not a real event. This box is not copied. Replace the notes above with your own before you paste the prompt.
Ideas only, not bookings. No ages, sizes, prices, or owned garments were supplied beyond the three preferences, so every clothing note means "something that person already wears." Theme A, Open-shelf observatory. Burden: medium. Someone must cut or draw a few paper stars. That is a small prop, so it is the heavier option. Stars adult: night watcher, darkest existing clothes, one paper star held at the waist. Low-effort alternative: no paper star, dark clothes only. Books adult: shelf partner, existing clothes, one book they already own. Low-effort alternative: no book in hand. Minimal-accessories adult: lamp minder, everyday clothes, no added item. Low-effort alternative: the same. No-costume role: guest, ordinary clothes, still welcome in the photo. Theme B, Matching night colours. Burden: highest. It asks the group to hunt for similar colours. Wardrobes were not listed, so this may fail. Stars adult: dark layer if they already own one. Low-effort alternative: whatever they are already wearing. Books adult: one owned book plus the nearest dark layer. Low-effort alternative: book only. Minimal-accessories adult: no accessory, even if colours do not match. Low-effort alternative: skip the theme piece entirely. No-costume role: guest in unchanged clothes. Theme C, Same evening, three jobs. Burden: lowest. No new objects are required. Each role uses existing clothes. The book is optional and only if that adult already has one. Stars adult: night watcher. Wear the darkest existing outfit. Distinct silhouette: the darkest full figure. Low-effort alternative: any existing outfit, no star prop. Books adult: page keeper. Existing clothes, one book already owned, held at waist height so the face stays clear. Distinct silhouette: a person with a book at the side, not in front of the face. Low-effort alternative: talk about books and carry nothing. Minimal-accessories adult: quiet host. Everyday clothes, no accessory. Distinct silhouette: the simplest outline of the three. Low-effort alternative: the same, because minimal is already the preference. No-costume role: guest. Any of the three, or an unnamed extra person, may take this instead and wear what they wore that day. Participation stays optional. This role is not a prop and not a joke costume. Comparison, then pick: Theme B may stall on clothes you have not said you own. Theme A adds paper. Theme C needs no craft and no shopping. Pick Theme C. Group photo, faces clear: the three stand in one row, shoulder to shoulder, camera at face height. Book, if used, stays at waist level. No masks. Nothing in front of the eyes or mouth. Leave a small gap so each outline still reads. This is an arrangement idea, not a claim about your room.
