james090500 MinecraftCapes mod allows you to install your own cloak in Minecraft, and everyone who has this mod installed will see it, but, unfortunately, you need a License.
MinecraftCapes Mod for Minecraft 1.16.2/1.16.1/1.15.2
The installation of the skin is not very difficult, but at the moment it does not work with pirates, but if you have a license, then everything is quite simple.
1.16.2 – minecraftcapesforge1.16.2-v10
1.16.1 – minecraftcapesforge1.16.1-v10
1.15.2 – minecraftcapesforge1.15.2-v10
