Problem

• My Sim is not wearing their Standard Outfit but something random
• My Sim runs around naked

Cause

Seit Patch 1.31 you can add custom career outfits to your Sims

• Your Sim is assigned a random career outfit instead of the standard one, depending on what your Sim did last before starting a new career (Naked if they took a shower, graduation robe if they just graduated, ..)
• The lab table adds an extra career outfit to your Sim every time they use it.

Solution

• Add a second career outfit to your Sim and go back to the game. Then enter CAS again and delete said outfit. This should trigger the Standard outfit.
• Delete all extra career outfits that you did not create yourself and want to keep.
• Use the cheat unlockOutfits on to unhide the career outfits in CAS.
