Should the groom wear a tie or bow tie to his wedding?

The groom's choice of whether to wear a tie or bow tie to his wedding depends on the level of formality of the wedding and the dress code agreed by the couple.

If the wedding is formal, such as a black tie event, the groom really should wear a black bow tie with his tuxedo. A white bow tie can also be worn with a black tuxedo or black tailcoat for a white tie event.

If the wedding is semi-formal or casual, the groom could wear a traditional necktie with his suit or tuxedo. The groom could also choose to wear a bow tie if he prefers, but it's not necessary.

Ultimately, it's important to follow the dress code agreed by the couple and pay attention to the level of formality they want for their wedding to ensure that he is dressed appropriately. The groom should also consider the overall style and theme of the wedding when making his decision.
