This always befuddles me.
I ride the colectivos almost every day.
I look out the window, and I observe what locals are wearing.
I see encargados, dressed head to toe in Pampero work clothes (I love Pampero, and often wear it)
I see lawyers, dressed in fitted suits and shiny leather shoes ( I only have one suit here, a nice gray sharkskin, but I do have a couple of pairs of shiny black shoes)
I see skaters, dressed in cargo shorts and vans (I used to wear Vans, when I was much younger, but the flat soles make my feet hurt now. I do still have a pair of slipons stashed, though)
I see preppies, wearing Kevington chombas (golf shirts) and tailored patterned shorts (not a look for me)
I see pampas hippies, wearing bombachas, alpargatas, and tie died t shirts (I own all those things)
I see goths. Lots of goths, studded, platform booted, fake and real leather, with eyeliner (I seldom wear my really tall platforms, still own an original ramones style leather jacket though. Not big on eyeliner)
I see older dudes from the estancias, wearing those quilted jackets from Arandu, with elegant sneakers, and really tight fitting jeans, looking like a million dollars, because they are worth that, easy, just in cattle. (I have the tight jeans, but I am somehow missing the million dollars)
I see futbol fans, wearing either head to toe track suits, looking like russian mobsters, or basketball shorts and a boca jrs jersey, both enormous (again, not really my look, but I can dig it)
I see a million ordinary joes, wearing running shoes, jeans, and rock band t shirts. (not a big Nirvana guy, but I have all those things, although my sneakers are leopard print)
We wont even start on the womens clothes, except to say there are probalby twice as many different looks.
So- which of these looks is looking like a "local"?
I do know, if you want to be identified as a tourist, without doubt, you wear all expedition wear- shorts, long sleeved shirts, and floppy brimmed hats, from patagonia or north face or some other outdoorsy label, with each garment covered in pockets. Tourists and people on cruise ships are convinced that there are no pockets in Argentina, so they bring extra. Who, exactly, NEEDS 3 pockets on their hat?
They also wear 300$ climbing/running/orienteering boot sneakers that take a half hour to lace.
Antarctica starts here.
I will say, that in all my travels around Argentina, and every day in Capital, there are two things that pretty much all Argentines have in common-
1- good, recent haircuts. Everybody except destitute street people has been to the barber or the salon in the last two weeks. That includes goatherds in the andes, cartoneros, and everyone else.
2- clean, respectable shoes. I have seen, very rarely, a hipster, usually german, with intentionally worn and scuffed shoes. Every single Argentine I know always has great looking shoes, clean and polished if needed, blindingly white, unscuffed, and new looking.
You wanna look local, go to the barber (many now serve coffee or cocktails), and buy yourself some decent new shoes.
