Celebrity are a 5* line & most men ware a tux, with suit & tie coming in second.
I disagree with most men wore tux, We have sailed on millie and century and a good smart suit was the order of the day.
On our last few cruises there are fewer and fewer men wearing tuxedo's on our cruise out of 1850 passengers only saw 50/60 the rest were dinner suits or a lounge suit, the predominant outfit was the dinner suit with bow and tie with ladies some in long but the majority knee length outfits but still well dressed on the formal evenings. Despite the above comments I will still be taking my tux on our next cruise.
Tuxedo is the US term for the complete outfit that is properly called a 'dinner jacket' (or 'black tie') in the UK. So, I should be interested to know what distinction you are drawing between the two here!
Me too!! I was baffled, although some Americans refer a tuxedo to what we call a 'white tux'.
A nice smart suit will be ok. It seemed to be the older folks that wore tukes. On celebrity ships you can hire them, look at the info on their web site it will give you prices.
