Skins

Skins are textures which determine how a player appears in Minecraft: Pocket Edition. Skins were added in Update 0.11.0.

Default Skins
There are currently two default skins in the game-
 * Steve, the male model
 * Alex, the female model

Skin Packs
Mojang has released official skin packs containing a variety of skins, mostly based on one or more themes (eg. Star Wars, Marvel, etc). These can be either free or paid.

Custom Skins
It is also possible to upload a custom skin into the game if the player chooses to do so. They can do so using the Minecraft: Skin Studio Encore App. Another possibility is searching for skins online, downloading them to your device, and selecting custom skins then the one of your choice (you will have to search your photos)

Trivia

 * Skins were originally planned for Update 0.10.0, but were postponed as they were too buggy.
