Mom, I am with you 100%. I go on a cruise to relax and enjoy myself, not to look at other cruisers and judge them by how they are attired. The winds of change are blowing, and I feel like gliding right along.
It isn't just the under 50 generation who feel better when they are dressed casually on a cruise, but a whole lot of those over 50 like myself really hate wearing a coat and tie. I really don't know how I look, but I feel much better wearing dress slacks and a nice shirt to dinner.
I want to choose a cruise by itinerary,length of cruise, size and design of ship rather than by what dress standards the cruise line suggestd or requires.
Live and let live and you will live longer!
