Final Thoughts
The best best friend Halloween costumes are the ones that reflect the actual friendship.

A duo costume that tells a story is always more memorable than two unrelated costumes worn by people who happen to be standing together.

Common questions
What are the best Halloween costumes for best friends?
The best duo costumes are the ones that are instantly recognizable as a pair and reflect the friendship. Classic pairings like Thelma and Louise, Sandy and Danny from Grease, or a devil and an angel are perennially popular. Punny pairings like salt and pepper or peanut butter and jelly are reliably funny and easy to execute.
How do you coordinate best friend Halloween costumes?
Agree on the theme first, then divide the specific costumes. Make sure both costumes are at the same level of elaborateness — one person in a full costume and one in a half-hearted version looks unbalanced. Plan the costumes together and shop or make them at the same time.
