Quick answer
Do you have to dress for lifestyle cruise theme nights?
The answer
Usually not, although theme-night participation is a major part of many lifestyle cruises. Guests can often interpret each theme at their own comfort level by wearing a complete costume, matching the suggested colors, adding a simple accessory, or choosing ordinary evening clothing. Check whether any particular event has a required dress code. See Temptation's theme-night programme as one organiser-specific example.
