If you are so lazy that you want to use this method, go ahead. But be aware that there is no guarantee that won't glitch out or even work.
Also this will not look very accurate because of the workshop limitations. But, the good thing about this method is that it will work on most servers, so use this if you play a lot of multi-player.

WARNING: Incorrectly doing this might ♥♥♥♥ your GMod and you might need to reinstall the game when you fail to install the mod.

You need WinRAR for this
This method is better because it should always work, and the skin will be much more accurate, but this won't work on most servers, as this requires the server to also have the skin installed. But it works on single-player and on some servers that have this skin installed, which 99.999999999999999999999999999999999999999999999999999999% of servers don't.

Download the skin from this link below:

And now, you might be asking "why not just put this in a new folder in garrysmod\addons?"
The answer to that is that it won't work for all files, and it will look weird.

Now launch Garry's Mod and check if this works.

If yes, then you're good to go.

But if it looks ♥♥♥♥♥♥, then you're ♥♥♥♥♥♥.

If you hate this, or you ♥♥♥♥♥♥ up the installation process, there is a way to delete this.
First, open your GMod addons folder, which is in
Then delete the folders that start with OldGMod

Now go to and delete the folder

The final step is to open steam, open your library, right-click GMod, properties, local files, and verify integrity of game files or something, then wait 2 hours or something for it to finish, and launch GMod. If this didn't work, you're ♥♥♥♥♥♥.

If you are reading this, then you seriously ♥♥♥♥♥♥ up.

Uninstall GMod, and delete it from your steamapps\common because steam is too lazy to do it.
Then install it again. If this didn't work, you are seriously ♥♥♥♥♥♥.
