What is the etiquette for the groom's wedding suit?

Short answer

There is no strict etiquette for the groom's suit. The main rule is to dress appropriately for the formality and venue, and to coordinate with your partner so you both feel like a team.

Etiquette for the groom's suit has relaxed a lot in recent years. The old rule that the groom must wear a morning suit or black tie no longer applies. What matters is that your outfit matches the dress code of the wedding and the venue. If the invitation says black tie, wear black tie. If it says lounge suits, a smart suit in any colour is fine.

Coordinate with your partner. If they are wearing a dramatic gown or a simple dress, your suit should complement it, not clash. Look at the colours they have chosen and pick a suit that works with them. You can also match your tie or pocket square to a colour in their outfit.

Consider the time of day. Daytime weddings often suit lighter colours and less formal styles. Evening weddings can take darker, more formal suits. But this is a guide, not a rule.

You should also think about your guests. If the wedding is casual, a full three-piece suit may feel out of place. If it is formal, a casual suit may look underdressed. When in doubt, ask the venue or your celebrant. They can tell you what is typical. The most important thing is that you feel comfortable and confident.
