Do you want your sims to have more realistic-looking boobs (especially larger ones?) Then you NEED this breast slider mod by pirumxsim. You can alter your sim’s breast shape by moving left or right, or up and down using the CAS chest controls. This body slider works on teens through elders and only on female-framed sims!
Follow these steps to install Sims 4 Breast Slider Mod on your Sims 4 game:
Download the mod file from the link above. Sims 4 mods typically come as .package or .ts4script files.
Open your Sims 4 Mods folder. The default location is: Documents/Electronic Arts/The Sims 4/Mods
Place the downloaded file directly into the Mods folder. You can organize mods into subfolders up to one level deep.
Launch The Sims 4 and go to Game Options > Other. Make sure "Enable Custom Content and Mods" is checked.
Restart the game if it was already running. The mod should now appear in your game.
Important: Always back up your save files before installing new mods. After Sims 4 updates, mods may need to be re-downloaded or updated by the creator.
Platform
The Sims 4 (PC/Mac)
Pro tip: If a mod stops working after a game update, check the creator's page for an updated version. Broken mods can cause the game to behave unexpectedly.
