Assembling your Outfit with Pre made Clothing - Zachs-Kappler/Zachs--Clothing-Pack GitHub Wiki

I have included instructions for using any image editing software that can handle layers. I wrote these instructions with Gimp 2.8 and Paint.net in mind, but the instructions should be applicable to Photoshop.

Instructions:

1. Open your image editing software of choice.
2. Create a new project that is 64px by 32px or open the avatar you wish to add the clothing to.
3. Drag each item you wish to add to the layers pane. Don't forget to move the new layers so pants are under belts, shoes over socks, etc.
4. When satisfied with the order of your layers, export the project to a PNG file. If your are asked to merge layers, say yes.
5. Access Minecraft.net and replace your old naked skin with your new fully clothed skin. Enjoy!
