White clothing is especially associated with Brazil's New Year's Eve celebrations.
The color is commonly linked with peace, renewal, and wishes for a harmonious year. Many celebrants wear white at parties and public gatherings, particularly along the coast. The practice combines modern popular celebration with cultural influences connected to Afro-Brazilian religious traditions.
Rio de Janeiro's Copacabana beach hosts one of the country's most famous Réveillon celebrations. Crowds often gather in white, watch fireworks over the water, and make offerings or other symbolic gestures connected with hopes for the coming year. Clothing colors may also be chosen for additional wishes, such as love or prosperity.
White is a widespread custom, not a legal requirement or universal rule. Brazil is a large country with varied regional practices, so New Year's Eve traditions differ between cities, families, and religious communities.
