Idea for a pair of trick-or-treaters

COUPLESCOSTUME

Think of matching outfits that two people might wear together on Halloween, like a famous duo or complementary characters.

This clue plays on the idea of two people dressing up together for Halloween. "Pair of trick-or-treaters" hints at a duo, while "idea for" suggests a creative concept—here, a shared costume. The answer combines "couple's" (for two people) with "costume" to form "COUPLESCOSTUME," a common term for matching outfits worn by partners or friends during Halloween. The wordplay is straightforward, merging the two ideas into one compound word.
