CustomizeYourSkin

Customize your Minecraft skin with accessories, hats, glasses, and outfits — all in-game! You are changing the skin itself. You don't put clothes on top of the skin separately like in other mods.Everyone will be able to see the updated skin even without the mod installed.

Unfortunately, due to the peculiarities of Minecraft, you will have to log back into the server (or into solo mode if you are playing with a friend) so that everyone can see your updated skin. But in the future, when I finish the mod, I will try to make a plugin for servers that will update the skin for all players on the server.
