Nazaré is famous for its traditionally clad women who wear skirts with seven petticoats (one for each day). While the story is somewhat of an invention for the sake of tourism, there is an element of truth to it. In the old days, women would wait on the beach for fishermen to sail home. To keep warm in the face of a cold sea wind while staying modestly covered, they would wear several petticoats so they could fold layers over their heads, backs, and legs.
