Seabourn Cruise Line
About This Line
At least one formal night is standard on seven-night cruises and three to four nights, depending on the itinerary, on two- to three-week cruises. Men are required to wear tuxedos or dark suits after 6 pm, and the majority prefers black tie. All other evenings are elegant casual, and slacks with a jacket over a sweater or shirt for men and a sundress or skirt or pants with a sweater or blouse for women are suggested.
