White is the traditional color of clothing worn for good luck during Brazil’s Réveillon celebrations.
Brazilian New Year’s Eve, commonly called Réveillon, is strongly associated with wearing white. The color is widely connected with peace, renewal, and protection, and large crowds often gather on beaches dressed in white as the year changes. People may add other colors to express specific wishes, but white remains the standard visual symbol.
Many celebrations also include offerings to Iemanjá, the orixá associated with the sea in Afro-Brazilian religious traditions, especially in coastal cities. In Rio de Janeiro, people may go to the shore, watch fireworks, and cast flowers or small offerings into the water, although practices vary and religious meanings should not be reduced to a costume trend.
White clothing is a general Réveillon custom rather than a rule applying to every Brazilian. Regional traditions, family practices, and personal beliefs differ across the country.
