Getting What You Need

1
Download The Sims 4. This goes without saying. You do need a copy of The Sims 4 if you want to make clothing mods for The Sims 4. You can download it from Origin.com.
- You cannot install or create mods for The Sims 4 on game consoles. You can only do this on PC or Mac.

Download an image editor. You need a photo editor such as Photoshop to edit clothing textures. If you don't have a Photoshop subscription, you can download and install GIMP for free from gimp.org. It's a free and open-source image editor that has many of the same features that Photoshop has.
4
Download Sim body texture templates (optional). These weird looking image textures are used to map out where your clothing textures are placed on your Sims. There are four different image templates and UV maps. One for female Sims, male Sims, toddlers, and child Sims. While we won't be using these for this tutorial, you may decide you want to use them for more advanced options as you get better as creating clothing for your Sims. You can download these images on The Sims 4 Studio forum.

Open the Sims 4 Studio. It has a blue icon that says "S4S". You can find it in the Windows Start Menu, or the Applications folder on Mac.
- The first time you open Sims 4 Studio, you will be required to enter the location of your Sims 4 install, documents folder, and Blender 3D install location. Don't worry if you don't have Blender 3D. Just leave that field blank. The Sims 4 install location is C:\Origin Games\The Sims 4\ by default, and the documents location is D:\Documents\Electronic Arts\The Sims 4
2
Enter your creator name. Enter the name you want to use as your creator name in the field in the lower-right corner. You can use your real name or a nick-name. This is required.

Click CAS. It's one of the four blue buttons on the opening page of Sims 4 Studio.

6
Type a name for the file you want to create. This is the name of the mod that you will eventually create. Type a file name for the .package file you are creating next to "File Name".

Click Diffuse below "Texture". This displays the diffuse texture map in the lower-right corner. The diffuse texture map is the image that goes over the 3D clothing mesh in the game. The image in the lower-right corner is what the texture map looks like layed out as a flat 2D image.
10
Click Export. It's the green button below "Texture" in The Sims 4 Studio.

You can use the brush tool to add textures or patterns to the item, or copy a logo or image and paste it on to a T-shirt.

You can use GIMP from gimp.org. Otherwise, use any other photo editing software you come across.
