How fussy is Princess on the formal nights. Can a man get by with a blazer, slacks, and tie? Having been retired for nine years all my dark suits and my tux have shrunk in my closet. We're on the Star Princess on 2/2/10 for the cruise down to Antarctica. We generally avoid ships with formal nights doing mostly river boats (GCT nine times) or NCL that was lousy on our last trip.
