Black Tie

You’re in tuxedo territory here and a timeless black tux is the only way to go. Have your best black lace-ups shined in advance (patent leather shoes are traditional but not required these days). A bibbed tuxedo shirt is the most traditional and formal, while a covered placket or plain front is less formal and more modern. A peak or shawl lapel is the order of the day; a notched lapel is acceptable, but is best avoided if at all possible.
