Many cruises have a Formal Dinner where tuxedos would be appropriate. Choosing Formal Wear locally saves you time on the cruise and usually gives you a much larger selection. A black tuxedo is normally the most accepted attire, dinner jackets are also a great choice, or both if there are multiple nights for formal attire. Milroy's Tuxedos offers a cruise special as follows: 1 day price for up to 2 weeks and an extra shirt when requested (dependent upon availability of styles).
