In the Yo-kai Watch Busters games, costumes (Japanese: スーツ Sūtsu) are items that can be used to alter the appearance of a Yo-kai, changing their specific species of Yo-kai and their stats. Costumes can be removed at any time to revert a Yo-kai to its original form.
Costumes become available after unlocking the basement floor in the Busters House. After the player obtains their first costume, the vending machine in the wall of B1F can be moved to reveal a secret costume changing room.
