How to Edit Pre-Existing Sims

The Sims 4 doesn’t allow you to edit a Sim’s physical features after they’ve been created by default. However, thanks to cheats, you can unlock the CAS Full Edit Mode to tweak your Sim. Here’s how to do this:
Open the cheat console by pressing Ctrl + Shift + C for PC/Mac users or L1 + L2 + R1 + R2 for Console users.
Type in: testingcheats true and press Enter. This will activate cheats on your game.
- Type in cas.fulleditmode and press enter.
Next, left-click your Sim while pressing Shift to bring up the commands.
Next, click Modify in CAS.
This will take you back to CAS(Customize A Sim Mode), where you can edit everything, including facial features and body shape.
This feature works for everything from clothes and facial features to traits, aspirations, and modes. All you have to do is click on the respective tabs to make changes. For instance, to change the name of your Sim, click the name tab on the left corner.
Note that this process works for all players, whether you have custom content, mods, or game packs. Additionally, certain mods give you more editing control. These include MCCC, More CAS Columns, Stand Still in CAS, and Lumpinou’s Personality Mod.
Why Edit Pre-Existing Sims
Players have different reasons for wanting to edit pre-existing Sims during their gameplay. Some of the common reasons include:
To refresh a Sim’s wardrobe with new custom content recently added to the downloads folder.
To give their Sims a natural glow up after they age, especially when playing Legacy Challenges.
To give their Sims a new personality by changing their current traits and aspirations. This is highly beneficial if you want to test out a different storyline.
To give their Sim’s new hairstyles and makeup that refresh their look.
Regardless of your reason, you can easily learn how to edit pre-existing Sims to improve your game. This eliminates the need to create an entirely new Sim to fit your current gameplay. Whether you have one Sim or an entire household of Sims complete with a parent and child, you can edit each and every one to suit your storytelling and gameplay.
Basic Edits: Changing Outfits & Hairstyles

If your goal is to do simple edits on your pre-existing Sim, you don’t have to go through the entire process mentioned above. Simply follow these steps:
Click on a mirror or dresser.
Select “Change Sim” (for a full CAS mode) or “Plan Outfit” (to edit clothing only).
This will open Create-a-Sim (CAS), where you can change clothes, accessories, makeup, and hair.
Once you’re happy with your changes, hit the checkmark to save.
