The only thing better than having one best friend is having two amazing besties to make amazing memories with. When you're a trio of besties that do everything together, it's only right you keep the same energy during spooky season. Ofc, you've already planned out an itinerary of classic things like tuning into the best Halloween movies and making your way through frightening haunted houses, but what about the biggest night of the season? There's no need to rock a solo ensemble this Halloween when you've got two besties to create an epic trio Halloween costume right by your side.
Iconic three-member music groups can serve as trio costume inspo as well as beloved characters from your fave TV shows. You can even recreate childhood lullabies and rock nostalgic looks from your favorite decade. You can even use the name of your group chat as inspo for your squad's Halloween costume. Are you ready to have a ball with your closest friends this Halloween? Grab your two besties and get ready to slay All Hallow's Eve with this list of the best trio Halloween costumes.
