What are three important etiquette rules?

Answered by the UK Wedding Websites editorial team · Updated 2026-10-12 · For guests

Short answer

The three most important rules are to RSVP on time, dress appropriately and be kind to everyone. These three habits make the biggest difference to the couple.

Wedding etiquette is really about reducing stress for the couple and their families. The biggest pressures come from numbers, expectations and last-minute changes. You can avoid all of these with three simple choices.

First, reply to the invitation by the date asked. This helps the couple and their planner order the right amount of food and seats. If your plans change after you reply, tell them straight away so they can adjust.

Second, wear something suitable for the occasion and the dress code. A black tie wedding needs different clothes to a garden party. When in doubt, ask the couple or choose smart casual. Showing up looking tidy shows respect for the venue and the day.

Third, be kind to everyone, not just the people you know. Smile at the staff, welcome new guests and avoid gossip. Your mood sets a tone for your table and your corner of the room. Kindness costs nothing and is remembered for a long time.
