Do not look far, but read the address given by Mahmood Mamdani at the University of Johannesburg in 2010, which you can find here. He says, "...borrowed from the Islami madressas of the Middle East." and further that "..., modeled after the dress of the desert nomad, as the symbol of high learning."
