Current fashionable hat is called "Kan-Kan-Bou" in Japan. I heard this unique shape of hat is becoming popular around the world.
When I saw a model wearig this hat for the first time, I thought that it's pretty strange. However, I consider it's fashionable and cute as I get used to see this hat.
However, I had never seen such hat in Brazil. My Korean friend said it was famous in Korea, too. I hope I can get one in Brazil or in Japan.
