I have been battling random outfit changes for a couple of years with my own mods. Believe it or not, between weather, festivals, fake vampires, holidays, etc, there are over EIGHTY separate reasons (including "jobs"...not careers, mind you...things like barbecuing at the spice festival) for sims to change to a different outfit than the ones they are assigned. Eighty. And counting.
And the eyeball ring? Yeah, I have one sim I created as a poster boy to all outfit stupidity. He wears every accessory he can, including that ring, leggings, etc, along with a bicycle helmet and the tshirt with the shorts and fanny pack. And the star shaped sunglasses. His name is Max Maxis.
