Cummerbunds have dress requirements. Cummerbunds are only worn with bow ties.  If you choose a cummerbund, you must remember to have studs ready for your shirt.

Regular neckties are appropriate to wear with formal wear if paired with a vest.

Patent shoes are always the most appropriate footwear to wear with a black or white tie garment.

The three most classic formal wear coat styles are the double breasted coat, the one button coat with peaked lapel, and the one button shawl collar.
