Brazilian disguise

Anybody going to live in a different country has the problem of looking a bit out of place.
At the beginning it is because you are marvelled for everything you see: "Oh, a weird bird ... oh, a strange tree ... oh, a dodgy vagrant, ..."
You look lost even with a map: "Excuse me, could you tell me where is the north?"
And you get into the wrong toilets: "HIIIIIIIIIIIIIIIIIIIIIIIIII"

But once you have a bit of practise and you don't do all these sort of things how come the locals can still tell you are a foreigner with a quick glimpse?
(In some countries you cannot do much about it because it depends on your racial background, but not here in Brazil, specially in the south, as they have people descending from absolutely everywhere in the world)

So what is the trick?
Let me present you: THE HAVAIANAS! Yes, with this footwear (and as long as you don't open your mouth) you are going to fool even the customs police.

And the best thing is that these kind of flip-flops have many different uses ... they are like a Swish army knife, Brazilian style ... more on that topic in the future! :-)
