Answer: To many, the “Formal” term was misleading as it implies a specific type of dress (black tie or tuxedo) that has never been a requirement. “Dressy” still implies festive or dressy without misleading guests to bring attire the majority of guests don’t wear.
Guests will need to source options on their own for Dressy Nights, as Holland America Line does not provide formal wear. Guests who are taking a cruise can pack a bag with appropriate dress for the Dressy Nights on the ship and have the bag held for their return from a Cruisetour if traveling inland.
