Interesting word that has somewhat shifted its meaning.  Go back to, say, 1919 and the anarchist hysteria in western society.  A moral panic situation?  Black dressing in the modern jazz era was a touch subversive, as was the love of excess material in the zoot suit.  By my reckoning, the original peacocks and scooter boys followed that line.  Ivy clothes The Invisible Man, who, a la mod circa 60-62 (say) went discreetly about his business.  The individualist is - perhaps - subversive in his insistence on zig-zagging: I wear the bottom button of my cardigan fastened.  Functioning cuff buttons?  Sure, but barely anyone will notice. 
Subversion, now, to me, has become far more complex than during my teens.  Black style, black music, black dressing.  Short hair, mostly neat - focussed. 

The devil remains in the detail.  I can't stomach the bright lights of Brooks; I crave the dim interiors of good little shops still smelling of wool and leather.
