What is that item that you cannot get rid of, as old as it is?

An article of clothing that you won't get rid of because you like it so much. A pair of jeans, an old sweater, what is it?

I have a pair of pants, black cargo pants, that I like and cannot get rid of. They are really comfortable, but they look terrible. But I only wear them at home when I'm not going anywhere. I also have a pair of cream colored pants, made in France according to the manufacturer, that although faded, are so nice that I still have them. They are long, so they have grass stains at the bottom, and I can't wear them but I am debating on cutting them off at the bottom and hemming them some, so I can wear them again.
