Catsuit Mod & Other Outfits Add-on 1.0.0

Where in the folder do I place those sir?

You can copy the zip file as-is to you Addons folder. BUT.. If it were me, I wouldn't.. Those all look to be default outfits sorted into folders, except for the first item: C90.R9CatsuitMod . Adding the entire zip file to your game would do nothing but slow it down, and only give you one outfit. To use C90.R9CatsuitMod separately, extract it to your Addons folder.
