Minecraft wiki entry for Player, associated text: In Bedrock Edition, players can change their character's appearance from the Main menu or Pause menu -> Character where 5 character slots are shown. Edit Character will open the Character Creator where a skin, which synchronises between signed in devices, can be created by selecting pre-made components, altering their height, and select a slim or wide arm width. Players alternatively have the option select from Classic skins within Skin packs obtained from the Marketplace or, for the Windows 10, iOS/iPadOS, and Android versions of the game, import a PNG image file. Classic Skins will not synchronise between signed in devices.
Players can also choose 6 Emotes per character slot and select or remove a cape.
