Cruising with a gentleman friend on the Costa Atlantica, Jan. 25.04. We are wondering what the majority of men wear to the Captain's Dinner and any other formal dinners/events onboard. Do the majority wear tuxedos, suits or sport jackets and slacks? If the attire of preference is a tuxedo, can you rent them onboard and if so, what is the procedure? To all those who reply, thank you for your assistance!
