Answer: Yes, some refinements were made to improve consistency and the policy now reads:
Shirts/cover-ups and footwear are always required indoors. During daytime, dress is casual.
Most evenings smart casual attire is appropriate. Shorts, pool and beachwear, distressed jeans, and men’s tank tops are best left to the daytime and are not permitted in table service restaurants.
Dressy Nights evoke the grand traditions of cruising as guests dress to impress for special events on board, including our five-course gourmet dinner in the Dining Room. For gentlemen, collared shirts and slacks are required in all fine dining restaurants.
The dress for each evening is listed in the Daily Program and on the Navigator App.
