There is a variety of cosmetic items for use in Fortnite. These came from various sources, including, but not limited to Battle Pass seasons, a Twitch Prime Membership, buying a Starter Pack, and the Item Shop. You can gift cosmetic items using the Gifting system. Owned cosmetic items are stored in the Locker tab, in which players can freely switch between matches.
The types of cosmetic items are: Back Blings, Emotes, Emoticons (Emojis), Gliders, Harvesting Tools (Pickaxes), Loading Screens, Music, Outfits (Skins), Contrails (Skydiving Trails), Sprays, Toys, Umbrellas, and Wraps.
Some outfits and back blings are also tied to heroes in Fortnite: Save the World. Cosmetic items are not always available.
From Season 10/X onward, cosmetics such as Outfits, Back Blings, Emotes, Emoticons, Music, Loading Screens, Harvesting Tools, Sprays, Toys, and Wraps are available for Save The World players.
