There has been some discussion about formal nights and the prevalence of tuxedos. On the Millennium 14 day Baltic cruise, we had 3 formal nights (50%-70% wore tuxedoes), 4 informal (90% wore REQUESTED coat and tie) and 7 casual (10% wore coat without tie). Even some of the small children wore tuxedoes on formal nights.
This cruise I decided to rent my tuxedo from the cruise line as we anticipated running out of luggage space. For $75.00 one receives 1 black tuxedo jacket, 2 white formal shirts, 1 pair black formal (striped seam) pants, 1 bow tie, 1 cumberbun, 4 shirt studs and a set of cuff links. The quality of the rental was good (see attached photo). I used the cleaning service on ship for the formal wear and was satisfied.
I would recommend clip suspenders (either bring your own or rent from the formal company) for the pants!
On formal nights, the staff wears WHITE tuxedo as to be different from the passengers (a nice touch). We noticed only a few passengers with white dinner jackets.
The formal atmosphere was appreciated by my wife.
The only complaint was the scheduling of the formal nights (which will vary by cruise itinerary). In the Baltic cruise, two of the formal nights were the second and fourth day!
We enjoy the upscale Celebrity formal nights and hope they continue!
