Outfit
| Outfit | Trivia |
Many Operators in Arknights have various outfits or skins that changes their appearance to a unique feel and look with various themes depending on the Operator and the outfit in question. They are designed/produced by various Terran fashion brands and franchises, and tend to be designer clothes than practical battledresses such as those from the Pioneer and Striker brands, although some outfits blend elements from both, notably those from the Bloodline of Combat brand.
Some outfits also give special effects during gameplay including changing the appearance of summons tied to the respective Operator, but these are purely cosmetic and do not affect the Operator's performance in any way.
Most outfits are available in the Outfit Store, bought with 
Originite Prime or acquired by using 
Outfit Voucher (although certain limitations apply for this), and some are awarded from various events. It is highly recommended for players to save up their Originite Primes whenever possible to buy outfits for their favorite Operators to make the most of them.

Unique
Certain outfits also have unique features that makes them much more valuable and provide greater aesthetics.
Dynamic art
These outfits have a dynamic (animated) artwork, popularly (yet incorrectly) known as Live2D,[1] which is played when the outfit is displayed in the Store, main menu, and Operator information screen. Since this may strain the performance of certain devices, the player can have dynamic art outfits only animated on the main menu or turn their animations off altogether (thus only the static artwork that will be displayed as usual) in Options.

Special
These outfits, in addition to having dynamic art (see above), also has a special animated scene when acquired and changes the respective Operator's dialogues to new ones reflecting the outfit's theme when worn.
