I don't mind dressing up for dinner but prefer to wear casual clothes for the rest of the evening. Is it okay to attend the shows on Celebrity after dinner in casual attire?
The stated policy is that the prescribed attire applies thoughtout the ship except in the buffet area, which becomes the "Casual Dining Boulevard" at night. The reality is that enforcement varies. If you change before the show, you may be turned away and you may not.
That said, it's pretty obnoxious to put the cruise line in the position of having to take action to enforce the prescribed dress. People who have true class comply with the dress code without question or book on a line that does not have formal nights. People who book a cruise on a line that has standards of dress and then don't conform prove only their ignorance, arrogance, and total lack fo class by doing so.
