Not like the old Victorian Days!
Look presentable........No swimsuits, wet clothes or jean shorts!
Have seen plenty of women very comforatble in their khaki shorts, casual sundress, and nice beach cover dress. Be comfortable.
*Struggling to tesist the to make caustic comment to the effect that you should wear your own clothes and let Jean wear hers... *
Except in Alaska, where the temperature is pretty cool in the Inside Passage, you probably won't find very many people wearing jeans anywhere aboard a cruise ship duirng the day. Shorts or, for ladies, sundresses are the rule, excpet around the pool area where swimsuits are prevalent.
We did high tea on the Carnival Pride and people basically wore whatever they already had on that day and I saw alot of shorts! I say if you want to dress than dress and if not don't, it is your vacation.
