Panties

Panties are a special type of accessory each student wears in Yandere Simulator. At the beginning of each day, Yandere-chan can change her panties by interacting with the drawer in her bedroom. Yandere-chan can only put them on in the daytime. Different types of panties allow her to carry out various tasks with more ease, such as earning a reputation bonus or being able to commit murder with less risk of getting caught. In future updates, only some panties will be in Yandere-chan's closet at the start of the game, and the rest will either have to be bought or unlocked. When walking to the drawer, a pink HUD pops up saying "Change Panties".

'''NOTE: At the moment, the Pink Panties are the only panties that are not yet functional. In the future, they may be replaced with ones that will enhance Seduction skill.'''

Panties also serve as another gameplay element: if the player takes pictures of other girls' panties with the phone and sends them to Info-chan, they can exchange them for various favors.

Rival Panties
In the future, every rival will have unique panties. The player will be able to unlock her panties by eliminating her. Wearing them will grant a unique unknown buff that no other panties have.

Original Panties
These panties were removed in the May 3rd, 2015 Build and replaced with newer, better models. The Spats, Cute Bear Panties, and the Stealthy Black Panties were present, but remain the same as the updated panties.
