I am taking this directly from the cruise booklet we received last week for our upcoming cruise:
Cruise Casual no swimwear or tank tops
Pirate or Tropical Night (on most cruises)
Dress Up jacket for men, dress or pantsuit for women
Semi-Formal suit/jacket for men; dress or pantsuit for women
Formal tuxedo or suit for men; gown or dress for women
Palo shirt or jacket for men with dress pants; dress or pantsuit for women. Please, no jeans, shorts, capri pants, flip flops or tennis shoes.
Now the dress code for men in Palo gave my husband a laughshirt OR jacket.
