The other day I was talking to a friend who lives up north Finland, in a very beautiful town by the sea. I wondered if I would be arrested if I went swimming with a brazilian bikini and then he said I wouldn't be arrested even if I went to swim naked.
That sounds so fun. It's like, you only go naked here if you're 100% sure that no one will see (and you might not want to do it in Amazon, because of candiru fish (google it ;) . But getting naked in front of our friends or strangers, whatever... it has mostly to do with sex. Even beach bikinis are made to seduce.
We once had a President who tried to rule over a bikini-size law. I swear he put supervisors at beaches. His name was Jânio Quadros and he was little bit crazy and alcoholic, but, who cares? He's dead now.
We can't go naked around... But we can wear the bikinis we want.
