what is black tie optional

"Black tie optional" is a dress code that is often used for formal events such as weddings, galas, or upscale parties. It means that guests are encouraged to wear black tie and formal attire, but its not mandatory. Men are requested to wear a tuxedo, but can opt for a dark suit. Women can choose either a formal evening gown, a shorter cocktail dress, or dressy separates. The "optional" part is for the benefit of the guests, who can choose to dress in black tie attire or wear something slightly less formal. However, its polite to dress as formally as you feel comfortable doing at a black tie optional event, especially if the couple and their wedding party will be dressed in black tie.
