Formal or Black Tie Optional
What to Wear:These dress codes are typically reserved for the evening and indicate that something slightly less formal than black-tie is acceptable. So, a tuxedo isnāt required, but the event is still formal enough for one to be appropriate. You still have the option to wear a tuxedo, but a dark formal suit, white shirt, and dark tie will likely be the most popular choice. A tie is a must here.
