- For the version in Plants vs. Zombies Online, see Costumes (PvZO). For costumes found in the code, but have yet to appear in the game, see Plants vs. Zombies 2/Concepts/Costumes.
Costumes are cosmetics that the player can earn in Plants vs. Zombies 2. Every plant has a costume, except for Imitater, Marigold, Power Mints, Dazey Chain, the Vine Plants (Blastberry Vine, Pyre Vine, Pumpkin, and Shine Vine), and Ultomato. In the Chinese version, costumes are used to boost Plant Food effects. To Cherry Bomb, Cycloque and Grapeshot, they were used to boost them as they do not have Plant Food.
A costume changer can be used to set whether the plant would wear its costume or not, except for the limited-time costumes of Sunflower, Peashooter, and Wall-nut. It can also change the costumes of the plants if there were more than one costume obtained. Depending on the costume, costumes could be obtained in piñatas, Señor Piñata, Mystery Gift Boxes, or the store (prior to the 5.7.1 update, but returned in 6.5.1).
