Oceania Cruise Line has a casual dress code that is akin to country club or resort-style attire. Although evening dining venues do require adherence to the country club casual dress code, the atmosphere on the ship is more laid-back than other upscale cruise lines. Dressy shorts and casual shirts are acceptable in the Terrace Cafe during the evening, and room service is an option for those who prefer to dress even more casually. However, shorts, casual jeans, t-shirts, athletic footwear, and sandals are not allowed in the Grand Dining Room, Jacques, Red Ginger, Polo Grill, Toscana, or Tuscan Steak.
There are no formal nights on Oceania Cruise Line.
Jeans, shorts, T-shirts, and tennis shoes are not permitted at dinner or in any public areas after 6 p.m. Tank tops and swimsuits are not suitable for any of the onboard restaurants at any time.
