Well, let's not forget that we're dealing with what basically amounts to an urban "hip hop" style guide. To put things bluntly, I've seen that whole subculture embrace FAR stupider things, and the paramilitary rebel look has always been popular with certain segments. It's noteworthy for example that 50 Cent's "G-Unit" doesn't just have one meaning to it, and both Gangsta unit AND Gueriella unit are intended due to the whole urban gueriella thing and the implication of fighting against "the man". Then of course you have groups like "The Black Panthers" which have been increasing in their activities since the Obama election, ever since they were threatening people at the polls (which was on the news) they seem to have had an increased prescence and they very much do the "commando" thing. The popularity of Modern Warfare 2 in the mainstream makes this hardly a big surprise, even if it is a bit silly.
Speaking for myself though, I've always thought Marc Ecko was basically a dweeb. This is a guy who claims to embrace the hand to mouth urban rebel, producing games like "Getting Up" which was about Graffiti artists, but does so in order to pimp fashions that basically amount to paying a small fortune to look like someone who stepped out of a ghetto.
I suppose I do sort of understand the mentality to an extent, dressing like a bum while sporting thousands of dollars in jewlery in the ghetto being intended to be a statement about "keeping it real" and "get rich or die trying" (and often talked about), I suppose the "bum rags" costing a small fortune themselves can be seen as an extension of that for those who for whatever reason don't feel it's ridiculous.
Still, I ultimatly feel you can look like a cut rate paramilitary bravo, by hitting your local army surplus store. Oh granted, you won't be able to prove your not REALLY a bum for whatever reason by showing off your Marc Ecko approved labels... but honestly how many people are actually going to care unless you start talking about how you actually paid those prices.
... and honestly, I think the fact that anyone wants to look like ANY kind of third world criminal(from anywhere) kind of disturbing. I mean I would think the idea would be to grow beyond that id you had the means to. I mean frakk, for 800+ dollars you can get a pretty nice suit.
