Royal Caribbean updated the dress policy on its website:

The new rules are:

• For formal nights, the cruise line recommends “suits and ties, tuxedos, cocktail dresses or evening gowns.”
• For smart casual nights, “think of this as a step up from your typical dinner wear” and wear “collared shirts, dresses, skirts and blouses, or pantsuits.”
• For casual nights, Royal suggests “jeans, polos, sundresses and blouses” but asks guests to “keep swimwear to the Pool Deck.” Shorts and tanks will be accepted for breakfast and lunch, but not in the main dining room at dinner.
