Everything's better with a buddy — Halloween included. Think about it: Running from door to door and tracking down your neighborhood's very best Halloween candy (hello, king size candy bars) is way more fun when it's shared with the person you love most. Matching Halloween costumes are an easy way to take things to the next level. While it may seem like a nightmare to get your kids to settle on a specific theme — astronauts? vampires? pirates? — it'll turn out to be less of a headache in the long-run because you'll be able to take care of two (or three) costumes at once.

Browse through these brother Halloween costumes to get serious inspiration for their 2021 looks, everything from classic Disney characters to superhero duos. Here, we've rounded up a mix of store-bought and homemade Halloween costumes that will get everyone in the spooky spirit, stat. It doesn't matter if you're dressing up toddlers, kids or teens — these ideas are perfect for siblings of all ages and groups of all sizes. But if you have other kids to sort out, consider these sweet sister costumes or make it a family affair with an epic siblings costume.
