As you've probably read on this thread, there are a lot of explanations for baggy pants--probably some urban myths included.
Personally have heard that it comes from prisons where belts aren't allowed so that prisoners don't hang themselves (or others) or garret people. If the pants they issue you are too big, then they'll tend to sag.
