Are people wearing khakis and collared shirts every night? Is that just a dinner thing and then people go to bars in shorts? Whats the attire like?
yes, it is quite acceptable to wear docker type pants and collared shirts, either sport shirts or polos to dinner followed by shorts later if you want. I will say, sometimes in the evenings the ship is a bit too cold for shorts, but there is nothing wrong with you wearing them if you are comfortable.
