I gave up on conformity a long time ago (I suck at it) but I didn't strive to be a non-conformist (I would have preferred to be normal).
Result? I've found that the opinions of others are all over the map. I stand still, they do the moving.
For example, there was a time when everybody was wearing these glasses with really narrow lenses, like horizontal strips of glass. I hated them. I wanted the kind of glasses I've always worn--thick frames, big lenses.
I get out to California, and for a year or two, people were complimenting my glasses.
Now nobody says anything about them.
Crap like that. I don't care. Then there are other, far more important things that matter... and if you are true to yourself, the rest of the world may or may not like you for it; but at least you don't hate yourself.
Anyway, as for the "hipster effect", maybe it just so happens that there are only so many generic categories. The odds that you'll really stand out for anything just aren't that great. In fact, the odds that you'll even be perceived as unique aren't that great. I've had people tell me I look like somebody I know on a number of occasions over the years. It has happened when I had short hair and a mustache. It has happened when I had long hair and was clean-shaven.
I care more about the price of gas.
