In Brazil's Réveillon celebration, white clothing is traditionally worn to symbolize peace.
Brazilian New Year's Eve celebrations are often called Réveillon, a name also used in other French-influenced cultures for a festive New Year's meal or party. In Brazil, wearing white is especially associated with hopes for peace and renewal as the old year ends.
The custom is particularly visible in coastal cities, where crowds gather near the sea. In Rio de Janeiro, the Copacabana waterfront is famous for concerts, fireworks, and large public celebrations. Many participants also make offerings or prayers connected with Afro-Brazilian religious traditions, although practices differ among individuals and communities.
White is not the only color with a popular meaning. People may choose other colors to express wishes such as prosperity, love, health, or energy. Because clothing symbolism varies, white is the canonical answer for peace, not a claim that every Brazilian wears white or that the practice has only one religious origin.
