A lady brings a drink to a seated couple comprised of a woman wearing a long white dress and a man in a dark suit.
A lady brings a drink to a man and wife seated.
Just because a woman is wearing a long white dress and is with a man in a dark suit, that does not mean the woman is the man's wife. The fact that a lady brought the man and woman a drink does not imply that the man and woman were seated.
