Just to comment on one point only…,My husband wore his navy blazer, grey dress trousers, white shirt, silk tie & pocket square to LaDame on several formal nights. We were always welcomed graciously by name & felt more than appropriate. We were on the Muse Sydney to Auckland for several weeks in Dec 2019. The ship was predominately Australian & American & British, in that order. Seemed like the British wore more tuxedos & gowns. The rest of us were just slightly more dressed down. The tuxedos & gowns looked great but so did everyone else in their dark jackets, suits & elegant cocktail dresses. Everyone seemed to having a great time, I know we did. On another note, my husband who enjoyed a fine cigar in the Connoisseurs Lounge was always welcomed to sit with the tuxedo clad lads. Great conversation & single malts. Came “home” very late.
