Some people give away their old clothes that are torn and scratched to charity. I prefer sleeping in my old clothes compared to thin pajamas as my clothes are thicker and warmer.
Sometimes at home I wear my old/torn clothes but just inside the house because I don't want to spoil or dirty my formal clothes. By making use of your old/torn clothes you don't have to throw them away and unnecessarily produce waste until they are really unusable.
At other occasions you can use your old clothes when doing messy work such as painting or cleaning a certain place. You can also use them when cooking so any spilled or frying food comes at your already dirty/used clothes.
