There really isn't any inforced dress anymore. Especially on a Caribbean sailing. That itinerary so far has been Wecome aboard, Italian, french(formal), Caribbean, Mexican, can't remember nt 6, and bon voyage night 7. Night 3 French is the formal. Again, it's name only. If you want to dress fine, if not don't. There is a second dress your best. It's night 5 or 6 but I can't remember off hand. The dates I gave are the weeks cruise compass you need to search for, for more info. I got mine by reading the app everyday of the March 5th sailing as it happened.
