Daytime: By day, casual attire goes, so shorts, jeans, capris and tees are just fine. By the pool, of course, it's bathing suits and cover-ups; inside the Lido restaurant, shirts, cover-ups and footwear (including flip-flops) must be worn at all times. If you prefer to stay in your bathing suit, just bring your plate to one of the many tables and chairs outside.
Evening: Most evenings are Cruise Casual, which means slacks, khakis, jeans (no cutoffs), dress shorts (long) and collared polo shirts for men and casual dresses, skirts, pants, capris, dress shorts, jeans (no cutoffs), blouses and tops for women. Other nights are Cruise Elegant (once during two- to five-night cruises; twice during six-night or longer cruises) when you can don your elegant attire if you choose. Formal attire for men could include dress slacks and dress shirts (sports coats are suggested but hardly worn); while a suit or tuxedo would be appropriate, we never spotted anyone that formally attired. For women, cocktail dresses, pantsuits, skirts and blouses, or evening gowns are acceptable.
Not permitted: Not permitted in the dining rooms are cutoff jeans, men's sleeveless shirts, gym or basketball shorts, baseball hats, flip-flops or bathing suit attire.
