Attire ranges from Casual to Formal Optional. Casual wear is appropriate for daytime on board or ashore, and consists of resort-style outfits. Casual wear, including shorts and jeans, is not considered appropriate after 6:00 p.m. Evening attire falls into one of two categories, Elegant Casual and Formal Optional. Elegant Casual wear includes skirt, or slacks (no jeans) with blouse or sweater, pant suit or dress for ladies; slacks (no jeans) and collared shirt for gentlemen. Sport jackets are optional. While Elegant Casual is always appropriate, during Formal Optional evenings featured on longer cruises, guests may opt for a more formal choice of clothing including gowns and cocktail dresses for ladies; tuxedos, dinner jackets or dark suit with tie for gentlemen.
