Costumes

Outfits are sets of clothes for the Beheaded. They are unlocked by finding their blueprints and unlocking them from the Collector with cells like all other upgrades or items.

Once at least one new outfit is unlocked from the Collector, the player can change outfits by entering the Tailor's shop at the start of Prisoners' Quarters.

Outfits change the colors and sometimes model of the player's appearance. Some specific outfit elements, like the Concierge outfits' shoulder plate, changes color depending on the player's gear and action. Many outfits reference enemies (e.g. Ninja Outfit), bosses (e.g. Temporal Outfit), fictional characters unrelated to Dead Cells (e.g. Piccolo from Dragon Ball), or the game's developers (Carduus Outfit).

All outfits are purely cosmetic, with the exception of the Cultist Outfit, which is required to enter the Undying Shores from the Fractured Shrines for the first time.

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

For outfits dropped by enemies, the Hunter's Grenade can be used. Unlike most blueprints, some outfits will only drop from enemies with a certain amount of Boss Stem Cells active, even if those enemies can be found at lower difficulties.

Most bosses drop up to 5 outfits, one for each difficulty level from 0 (any) to 4+ BSCs. The outfit of the lowest difficulty will always be found first; the 0 BSC outfit will drop before any others even if the player is on Nightmare difficulty.

Trivia

 * While all costumes are in the base game, some of them cannot be legitimately obtained without installing the Rise of the Giant DLC, the Bad Seed DLC, the Fatal Falls DLC, or the Queen and the Sea DLC.
 * Outfits that drop from Mama Tick, the Time Keeper, the Servants, and the Queen give the Beheaded a female body.
 * While Conjunctivius is canonically female, her outfits do not have a female body.
