American culture isn't 'mass-market' though, mass-market clothes exist everywhere and so does exploitative governance, consumption, etc. The fact that some of that clothing makes it over to remote regions doesn't mean they're suddenly going to be permeated with 'American culture', they aren't cavemen discovering fire. It's just an item of clothing, albeit one that somehow found its way into their particular place of residence. Turkish bazaars are chock-full of these, maybe her dad went to one in a big city and brought this to her to wear. Does that mean she's somehow aware of capitalism, mass production, or American culture?
