Interesting article and its something that crosses a few of my interests with film production and fashion. I remember a few years ago rubbing sandpaper and dirt on my jeans to make them look "authentically" distressed (then I got a job where I can't keep my clothes hole-free to save my life).
For all the flack that you can throw at the series, I remember the later Harry Potter movies being another great example of this. I forget exactly where I saw this, but I remember one interview with a wardrobe assistant for the last movie showing off an entire rack of about fifty versions of his being jacket in various stages of wear.
