- This article is about the Mii Fighters' alternate costumes in Super Smash Bros. Ultimate. For other characters' alternate costumes in Super Smash Bros. Ultimate, see Alternate costume (SSBU). For the Mii Fighters' alternate costumes in Super Smash Bros. 4, see Alternate costume (SSB4)/Mii Fighter.
The Mii Fighters' various costume options are distinct from how other characters' alternate costumes work, as they can be purchasable from the Shop, found behind certain Challenges, or found in treasure chests in World of Light.
As it was in the previous game, while Headgear can be worn by all Mii Fighters, the Outfits are more selective.
Headgear
There are a total of 121 different headgear, including the 'None' headgear.
Many of the hats that were in the original game were based off of hats present in the StreetPass Mii Plaza.
Outfits
There are a total of 134 outfits, comprised of 52 Brawler, 43 Swordfighter, and 39 Gunner outfits.
