“Black Tie Optional” ?

The question has been asked If an invitation reads “Black Tie Optional” what does this mean?  This usually means that the host would like men to dress up in a tuxedo and women in an evening gown, but doesn’t want to enforce it. Should you own a tux then you should wear it to the event! If you don’t, and don’t want to rent one, then a dark gray or black suit, white dress shirt, and an elegant solid color tie (best are black or silver) will be a good alternative with a white or silver pocket square.
