Unfortunately, for Minecraft Java Edition, there are no skins that will automatically incorporate a cape. However, in Bedrock Edition, there are some skin packs that come with capes included.

Skins and capes are pretty common in Minecraft. Most gamers don't use the standard Alex or Steve skin that the game provides.

How to earn the Yearn Cape Upgrade Minecraft to the latest version (Bedrock or Java Edition). Access the Movie Live Event from the main menu (Bedrock) or join the event server (Java).
