The only ones I know you can get a change from are Paul, the ghost from the nursery, one of the girls of the club, the couple from the bar and one of the teachers on the university from the post-game
That's what I mean, there's not a lot of them, so if you have an accident, intentional or otherwise, you got to cover a lot of ground just to get changed. And afaik you don't get a say in what you get changed into, so once you reach this "lock" it is rendering the wide variety of prints you can find null.
