The Code: Oceania keeps its policy simple and casual. Country club and resort-style attire are generally appropriate for both men and women. In all evening dining venues, passengers are requested to adhere to the country club casual dress code. (Think elegant casual, although some passengers choose to get dressier.) Shorts, casual jeans, t-shirts, athletic footwear and sandals are not permitted in the Grand Dining Room, Jacques, Red Ginger, Polo Grill, Toscana or Tuscan Steak.
