On our last cruise with another line we dressed up for formal night. Me in a long sparkly dress and my other half in tux and bow tie. We were in the minority, although enough people had made the effort so we did not feel out of place. While walking through one of the lounges a lady with a broad smile on her face stopped us. She remarked how lovely it was to see we had both made the effort and admired our clothes. I have no doubt she was 100% genuine, and it made our night.
