Hmm, maybe the European looking Brazilians, who tend to be the wealthiest in the country, have the time and money to go to casting calls and such. Also, the models are probably doing more international campaigns, in America and Europe, and most of the consumers of fashion tend to be whites, so they're trying to appeal to them. I do agree though, that there needs to be more indigenous and Afro-Brazilians models because they're also beautiful.
