Lice at the Portuguese Royal court = fashion

Notes:

On the ship Alfonso de Albuquerque, on which Princess Carlota Joaquina, wife of the crown prince, had traveled, a lice infestation had obliged the noblewomen to shave their heads and throw their wigs into the sea. Their bald heads were anointed with pig fat and dusted with antiseptic powder. This resulted in one of the most comic episodes in the history of the Brazilian court. To protect their heads when they disembarked in Rio de Janeiro, Carlota, her daughters, and other ladies-in-waiting wore turbans. When they saw the princesses dressed like that, the women of Rio de Janeiro assumed it was the latest fashion in Europe. In no time, almost all of them had cut their hair and were using turbans to imitate the Portuguese noblewomen.
