Dinning rooms have really become quite casual. Just back from Galaxy. Even wore jeans and shorts to dinner. A few years back, they refused to let you in for dinner dressed this way. Not anymore. If you want to wear bathingsuits, cover them with a pareo or warmup suit. Or eat at the buffet or at the grill on deck. Cruise attire has really become much more relaxed. Most men are opting to wear a suit rather than a tux and on informal nights, a jacket without a tie. Wish I had known this. I could have left the long formal gowns home. I never wore them. I wore what I brought for informal on formal nights. It was just right.
