Outfits (aka skins) are a type of cosmetic item players may equip and use for Fortnite: Battle Royale. Outfits are cosmetic only, changing the appearance of the player's character, so they do not provide any game benefit although some outfits can be used to blend in the environment. Outfits are based on the Character Models. Additionally, outfits can sometimes come with a Back Bling; the Back Bling can be worn independently of the outfit or not at all. Some outfits are also used as heroclass skins in Fortnite: Save the World.
Promotional Outfits are exclusive to the gaming platform that your account associates to. Platforms such as Playstation, XBOX, Nintendo and even Mobile devices such as Samsung have exclusive outfits if you buy their devices.
