Cunard Line said it would adopt a more informal dress policy on some nights, but keep the requirement for formal evening dress at least three times a week on transatlantic crossings and twice a week on other cruises.
Cunard said on other nights of the week, informal dress will include jackets for men, but ties will become optional.
Previously, Cunard had three evening dress categories: formal, semi-formal and casual elegant.
The changes will take effect before the Cunard ships set out on their main sailing seasons in April and May, Cunard said.
