In Brazil's New Year's Eve Réveillon tradition, white clothing is commonly worn to symbolize peace.
Réveillon is Brazil's major New Year's Eve celebration, especially prominent in coastal cities such as Rio de Janeiro. Many participants dress in white as they gather for parties, concerts, fireworks, and ceremonies at or near the beach. The color is widely associated with peace and hopes for a harmonious year ahead.
The tradition also reflects the influence of Afro-Brazilian religious customs, in which white has important ceremonial associations. Participants may combine white clothing with other colors or accessories intended to express wishes such as love, prosperity, or health. These meanings are popular cultural conventions, not a single compulsory national dress code.
Rio de Janeiro's celebration at Copacabana Beach is particularly famous, but Réveillon is observed throughout Brazil. Fireworks, music, offerings, and regional customs vary from place to place, while white remains the most recognizable clothing choice.
