What is the difference between a tuxedo and a suit?

A tuxedo has satin or grosgrain facing on the lapels and a satin stripe down the trouser leg. It is worn for black tie and formal evening events. A suit is the everyday and daytime formal option.

What shirt goes with a tuxedo?

A white formal shirt, ideally with a pleated or textured front and a spread or wing collar. Avoid button-down collars, which are too casual for black tie.

Bow tie or necktie with a tuxedo?

A black bow tie is the traditional and correct choice for black tie. A necktie with a tuxedo reads as a modern deviation and is best avoided for formal weddings.
