Banning Miniskirts

I was lecturing last week on Mill's harm principle and various applications, such as what he might say about mephedrone or cannibalism. Now it seems that there's another example: an Italian town that wants to ban miniskirts and low-slung jeans! Now, back in Mill's day, it would probably have been considered indecent to show off a bit of ankle, but arguably that's just the kind of society-regulating-morality that he was trying to resist (though there is a problematic passage about public decency). Maybe I need a new irregular series about Mill spinning in his grave...
