White is the color people commonly wear for New Year's Eve celebrations in Brazil.
The custom is especially visible at large coastal gatherings, including the famous celebration at Copacabana Beach in Rio de Janeiro. White clothing is widely associated with peace, renewal, and good fortune as people enter the new year.
Brazilian Réveillon celebrations often combine fireworks, music, dancing, religious observances, and gatherings with family or friends. At Copacabana, many people also honor Afro-Brazilian traditions by making offerings to Iemanjá, a deity associated with the sea, although practices differ among participants.
White is customary rather than compulsory, and people may add other colors for particular wishes. In popular color symbolism, different shades can represent hopes such as love, money, health, or luck. The widespread white clothing therefore reflects a cultural tradition of peaceful renewal, not a national dress code.
