Cunard is perhaps the most diplomatic cruise line when describing evening attire, saying: “If you want to make an effort in the evening you won't be alone.” Some evenings are designated “gala evenings,” but Cunard suggests themes like “Roaring 20s,” “Black and White,” or “Red and Gold” rather than publishing outright ...

Cunard Line is the undisputed champion of formal nights in 2026, maintaining its legendary "Gala Evenings" as a core part of the transatlantic experience. On a typical 7-night crossing on the Queen Mary 2, you can expect two or three formal nights where the dress code (tuxedos or dark suits for men and evening gowns for women) is strictly enforced in the main dining rooms and public spaces after 6:00 PM. In the ultra-luxury sector, Silversea also maintains a high standard, usually featuring two formal nights per week on their longer itineraries. While most mainstream lines like Royal Caribbean and Norwegian have moved toward "Cruise Casual" or "Formal Optional" nights, Cunard has leaned into its heritage, offering a level of traditional elegance that caters to travelers who enjoy the ritual of dressing up for ballroom dancing and gourmet dining. If you prefer a "black tie" atmosphere, Cunard is the only line that makes the tuxedo an essential part of your packing list.
