Dressing for a Disney cruise in 2026 is largely about "Cruise Casual" comfort, but requirements vary by venue. During the day, shorts, t-shirts, and sundresses are standard for exploring the ship. For dinner in the main rotational dining rooms, casual attire is still perfectly acceptable, though many adults choose to step it up to "smart casual" (think polos, blouses, or nicer jeans). The real dress codes apply to the adult-exclusive restaurants like Palo or Remy, where formal or semi-formal attire is highly recommended; men usually wear dress pants and a collared shirt (jackets optional), while women wear dresses or pantsuits. Don't forget to pack for "Pirate Night," where many adults go all-out in full costume to join the themed deck party and fireworks.
