What happens to old clothes?

[luscious_purple]

For years (since a spirited debate on one of my LJ posts, though I can't find it at the moment), I've wondered what happens to old clothes that get donated, but then rejected as unsaleable at a thrift store.

Well, this article provides some answers, although it's focused more on clothes that don't sell in the stores in the first place. Feel free to read and discuss.
