During the day, casual clothes are suitable. After 5.30pm, 'smart casual' clothing is required in the public lounges and restaurants or as published in the ship’s newsletter. On our cocktail nights, it’s time to get your frocks out and join in the fun! We suggest women wear an evening or cocktail dress and men wear a suit or similar (tie optional). On three to six night cruises, our P&O Gatsby Party will be held on the cocktail night. On cruises five nights and longer, one of the cocktail night will feature the Gatsby Party, so get into the groove for the evening and dress up as a fun flapper or wear a debonair vintage suit.
