Halloween duo or pairing costumes are most fun when they have a clear connection - think opposites, famous couples, complementary characters, or two versions of the same character. Planning a costume with someone else means you can split the budget, share a theme, and both look intentional rather than like you've matched by accident. Below are ideas for couples, friends, or family duos (including parent-child pairs).
Top tip: if you're a surprise pairing in real life, lean into unexpected duos - a professional wrestler with an office worker, a vampire with a vampire slayer, or a formal royal with a casual medieval peasant.
