Holland America's dress code for evenings includes formal optional and smart casual dress. The line refers to its formal evenings as "Gala Nights," and formal attire is known as "Gala Attire." Men are required to wear collared shirts and slacks in all fine dining restaurants, while women are encouraged to wear dresses, skirts, or slacks. Smart casual attire is a slightly more relaxed version of the same dress code and applies to all areas of the ship in the evening.
The number of Gala Nights varies based on the length of the cruise. A seven-day cruise features one Gala Night, two on cruises up to 13 days, and three on cruises up to 20 days.
For guests who prefer a casual option, the ship offers a buffet and room service, allowing passengers to relax in their comfortable clothes.
Holland America prohibits T-shirts, swimsuits, tank tops, and shorts in restaurants and public areas during the evening hours. However, jeans are not expressly mentioned in the dress code policy.
