Save it for good is a term I heard all my childhood. I had to change out of school clothes the minute I came home, Sunday clothes were only wore on Sunday. Good shoes were only wore with the Sunday clothes. I had to take care of what I had because more was not an option. That scared me to not want to use anything nice I had. When my great aunt died I found many drawers full of items being saved for good, Goodwill for most of them.
