In a little over a month, I will be going on a cruise on the Caribbean Princess. Since this is both my first cruise with Princess and my first 7 night cruise I wanted to get some opinions on formalwear. I know there will be two formal nights, so I wanted to mix up my formalwear a bit by adding a new tuxedo in for the second night. I am looking at an all white tuxedo. I know the white jacket, black pants option is acceptable, but would an all white tuxedo be acceptable on a Princess Cruise?
