What are some unspoken rules for wedding guests?

Short answer

Unspoken rules include replying to the invitation promptly, following the dress code, not wearing white, turning off your phone during the ceremony, and not making a speech unless asked. Guests should also bring a card and gift, and thank the couple afterwards.

The unspoken rules of wedding guest etiquette are about respect and making the couple's day easier. The first is to RSVP by the date given. This is not a suggestion; it is essential for the couple's planning. If you cannot attend, say so clearly and promptly.

Dress appropriately. Follow the dress code on the invitation. If it is not stated, dress smartly and conservatively for a ceremony. Never wear white or cream, as that is reserved for the couple. Turn your phone off or to silent during the ceremony. Do not take photos during the ceremony unless the couple has asked for them; the professional photographer is working.

Do not make a speech or propose a toast unless you have been asked. Do not bring a plus one unless the invitation says so. Do not bring children if they are not invited. Bring a card and a gift, even if it is small, and give them to the couple or put them on the gift table. Finally, thank the couple before you leave and send a thank you note or message within a few weeks.
