Appropriately enough for a city where the beach and warm weather play such an important role, casual dress dominates in Rio, although during working hours men will not feel out of place in a suit and tie and women in smart dresses or a suit. Few of Rio's night spots require formal attire.

For men, slacks and a sport shirt are sufficient; for women, casual attire is fine.

Women may appreciate having a shawl or cardigan in hand for the more heavily air-conditioned buildings, while a light sweater is all that is necessary for winter nights.
