Costumes

Outfits are different sets of clothes the Beheaded can wear. These outfits can be unlocked by finding their corresponding blueprints and unlocking them at the Collector with cells much like gear, mutations and other upgrades in the game. Once at least one outfit has been unlocked at the Collector, the player can change clothes by entering the Tailor's shop at the start of Prisoners' Quarters.

Outfits change the colors and shape of the clothes and the scarf worn by the player. In some cases, specific outfit elements (e.g. the Concierge's shoulder plate) can change color depending on the player's gear. Many outfits exist, in reference to enemies (e.g. Ninja Outfit) and bosses (e.g. Temporal Outfit) but also to fictional characters unrelated to Dead Cells (e.g. Songoku from Dragon Ball) or the game developers (Carduus' Outfit).

Obtaining outfits
Outfits can drop from enemies, bosses or can be found in secret areas around the island.

For outfits found on enemies, the Hunter's Grenade can be used. Note that unlike most other blueprints, some outfits can only be found by killing Enemies with a certain amount of Boss Stem Cells active, even if those enemies can be found at lower difficulties.

Bosses drop an outfit on each difficulty level from 0 to 4 BSCs. The outfit of the lowest difficulties will always be found first, i.e. the 0 BSC outfit will drop first even if the player is on Nightmare difficulty.
