I just returned from sea princess nov 4 - 11. Dress code is what every you want to wear. Formal night some people were not in suits or tuxs or gowns. Several times on casual night I saw several people at dinner in shorts and tee shirts. Nothing was said to them about there clothes in the dining room, so why not wear what you want, obiviously princess cares more about money than the proper dress on board ship. I have been on Carnival ships and have seen people asked to leave and return with proper dress. Dress in the lounges was also casual,I guess the elegance of cruising is another lost art in these days of casual dress.
