FROM CARNIVAL'S WEB SITE:

DAY
Casual attire is the order of the day. We suggest shorts, sundresses, tank tops, etc. for the ladies, and for men: shorts, polo shirts, T-shirts, etc. will do. We suggest you wear rubber-soled, low heeled or flat shoes for extra traction while onboard. The use of any footwear with wheels, including but not limited, to Heelys shoes, is prohibited on board our ships. For dining you may want to dress up a bit and/or bring along a light sports jacket or cardigan.

EVENING
Most evenings we have a Cruise Casual dress code, but there are two Cruise Elegant evenings throughout your "Fun Ship" voyage (Tuesday and Friday evenings), where you will have the opportunity to showcase your more elegant attire. For those who want casual attire for dinner time, the Lido Restaurant is open nightly, and it has a more relaxed theme. However, shirts and shoes/footwear (flip-flops) must be worn at all times inside the Lido Restaurant.

Cruise Casual Dining Dress Code:
Gentlemen - Sport slacks, khakis, jeans (no cut-offs), dress shorts (long), collared sport shirts.
Ladies - Casual dresses, casual skirts or pants and blouses, summer dresses, Capri pants, dress shorts, jeans (no cut-offs).

Not permitted in the dining room during the Cruise Casual dinner for ladies and gentlemen: shorts, gym shorts, basketball shorts, beach flip-flops, bathing suit attire, cut-off jeans, sleeveless shirts for men, and baseball hats.

Cruise Elegant Dining Dress Code:
Gentlemen - Dress slacks, dress shirts. We also suggest a sport coat. If you wish to wear suits and ties or tuxedos, by all means we invite you to do so.
Ladies - Cocktail dresses, pantsuits, elegant skirts and blouses; if you'd like to show off your evening gowns, that's great too!

While we are all dressed up, we will be taking our group photo on one of these "Cruise Elegant" evenings! I'm aiming to have this happen Tuesday evening.

Not permitted in the dining room during the Cruise Elegant dinner for ladies and gentlemen: shorts, gym shorts, T-shirts, beach flip-flops, bathing suit attire, jeans, cut-off jeans, sleeveless shirts for men, sportswear, and baseball hats.

Personally, I won't be wearing any evening gowns and Jeff won't be wearing a tuxedo. But if you have it, hey why not!
