I follow the suggested attire, i.e. cruise casual, semi-formal, formal and Pirate of course, the way I see fit, and I like to dress up for dinner (especially if there is an opportunity to get a decent picture with my family! I love heels and wedges, but also wore dressy sandals alot. I wore a maxi dress, of some sort, on cruise casual nights, full pirate costume on pirate night, cocktail dress on semi-formal and a long gown on formal night. (There was also a Halloween night where I wore my Belle costume to dinner). I have never seen, probably out of luck, any one in a wife beater! Our tablemates were always dressed nicely as well. When we traveled with my in laws, my mother in law wore capris or slacks with a nice blouse most nights.
