This bug has been driving me nuts for months, how about you? Well not anymore!
Download four mods from here (nerdfestival, blossomfestival, foodfestival + lampfestival) and this one here, and voilà! No more silly outfits!
Just thought I’d share because I wish someone had told me about these mods before =D
OH MY GOD YES!
