- 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/Upcoming content/Costumes.
Costumes are cosmetics that the player can earn in Plants vs. Zombies 2. Every plant has a costume, except for Imitater, Marigold, Ghost Pepper, Solar Tomato, and Electric Peashooter. Sunflower, Peashooter, and Wall-nut sometimes have costumes depending on the season or holiday. In the Chinese version, costumes are used to boost Plant Food effects (or upgrade an ability if the plant in question does not have a Plant Food effect).
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).

- Some plants' costumes may make references to other media or their respective Almanac entry. For more information, see the Trivia section of each individual article.
- In the Chinese version, the Sunflower, Peashooter, and Wall-nut now have permanent costumes, while some of other the plants have different costumes (Bloomerang, Split Pea, Citron, etc.), some plants' costumes are the same as they are in the international version (Iceberg Lettuce, Potato Mine, Lightning Reed, etc.), and some plants do not have a costume at all (Jalapeno, Power Lily, Tile Turnip, etc.).
- In the Chinese version, starting with the 1.2.0 update, there are 24 plants' costumes that the player gets from daily Yeti battles. Each costume affects the Plant Food ability, making them better.
- If the player exits a level with a plant without a costume planted in that level and gets that plant's costume at a Piñata Party, when the level is reentered, the already-planted plants will not have that plant's costume, but newly-planted ones will.
- In the Chinese version, during the 1.1 update, costumes are the first time reward in Zombot battles and Gargantuar battles.
- Starting from the 2.9 update, with the exception of Peashooter, Sunflower, and Wall-nut, plants that have costumes will have their portrait in their Almanac entry and the seed selection screen covered with what appears to be glass.
- As of the 4.6 update, all Almanac portraits are covered with this class substance, regardless if it is a plant or zombie.
- This substance has since been removed.
- Some plants, such as the Lily Pad and Spring Bean, have feminine costumes, despite being referred to as male.
- The costume shop gives the costumes names and descriptions.
- It also refers to Sun-shroom as female, despite it being mainly referred to as male in its almanac entry.
- Some costumes in the Chinese version are unused costumes from the international version.
- Prior to the 4.6 update, Winter Melon's Summer Nights costume, Grapeshot and Cold Snapdragon's costumes were the only costumes that could overlap the Costume Changer button.
- Moonflower's and Hot Date's costumes are the only costumes that are "held" by plants.
- In the International version, Ghost Pepper's costume is not obtainable, but it is present in the game's coding.
- Despite this, a few players have managed to obtain Pepper-pult's unused year round costumes normal and successfully through Piñata parties.
- Due to a programming error, Sunflower, Peashooter and Wall-nut's limited time costumes for 2016 Lawn of Doom event and Plants vs. Zombies Heroes event did not appear in the game, leaving them unused.
