Red clothing is traditionally considered lucky to wear for New Year's Eve in Italy.
Many Italians associate red garments, especially red underwear, with good fortune, love, and prosperity for the coming year. The custom is strongest around the transition from 31 December to 1 January, and some versions say the item should be new or received as a gift.
The symbolism of red has several overlapping associations. Red can suggest vitality, passion, and celebration, while older folk beliefs connected it with protection from misfortune. The exact rules are not universal: people may wear a red accessory, a red garment, or red underwear depending on family and regional custom.
This practice is one part of Italian New Year's traditions, which can also include lentils, cotechino sausage, fireworks, and public celebrations. The color custom should not be confused with a national dress code; it is a popular superstition and festive fashion tradition rather than a legal or religious requirement.
