The following clothing is in my game but I can’t find them in CAS or the launcher.
This dress by PeggySims contains the extra clothing.
They are wrongly categorized and don’t show in CAS cause it’s also categorized as hidden.
To get rid of the stuff, just delete the following file from your mods folder: peggyzone-sims3-f-Fclo0008-090812.package.
Unfortunately, these like to spread with Sims because of this issue: Downloads that are attached to Sims directly.
To check if you have them, you need either MasterController to turn off the clothing filter or use the cheat unlockOutfits on and then check CAS if they’re there.
