Etiquette for Bringing a Plus-One to a Wedding

Few lines on a wedding invitation cause as much quiet anxiety as the one that does, or does not, say "and guest". A plus-one is a generous gesture from the couple, and every extra seat has a cost in money, space and planning.

Handled well, bringing a companion adds warmth to the day. Handled badly, it can cause awkwardness that lingers long after the cake has been cut. These are the courtesies that keep it gracious.

Read the invitation carefully

The envelope and the invitation tell you exactly who is invited. If it is addressed to you alone, the invitation is for you alone. If it names you and a partner, or adds "and guest", you are welcome to bring someone.

Do not assume a plus-one because you have a partner, because you invited the couple's partners to your own wedding, or because you will know few people there. Couples often have to draw firm lines, and the guest list reflects choices they have already made.

If you are not offered one

It is rarely appropriate to ask. Many couples are working to strict numbers set by the venue or the budget, and a request puts them in the uncomfortable position of saying no.

There are gentle exceptions. If you are in a long term relationship that the couple may not know about, or you have a genuine practical need, a brief, warm note is acceptable. Something like "I would completely understand if numbers are tight" leaves them free to decline, and you should accept whatever answer you receive with good grace.

Reply promptly and precisely

Respond by the date requested, and include your guest's full name so it can appear correctly on the seating plan and place cards. If the couple have asked about dietary requirements, give your companion's as well as your own.

If you have been offered a plus-one but plan to come alone, say so clearly. A spare seat that is declined is easy to fill; one that is left empty on the day is not. If your circumstances change after you have replied, let the couple know as early as possible.

Choose your companion thoughtfully

Where the invitation simply says "and guest", choose someone who will enjoy the occasion and behave well in a crowd of strangers. A wedding is not the setting for a first date or for introducing someone the couple might find difficult.

If you are single, there is no need to bring someone simply to fill the seat. Arriving alone is perfectly proper, and you may well enjoy the freedom to mingle.

Brief your guest beforehand. Tell them the couple's names, the dress code, the order of the day and anyone they are likely to meet. A companion who arrives prepared feels comfortable and makes a better impression.

On the day

Your guest is your responsibility. Introduce them to the people at your table, keep them included in conversation and do not leave them stranded while you catch up with old friends.

Both of you should greet the couple and offer your congratulations, and your guest should thank them personally for including them. A single wedding gift from the two of you is perfectly proper, with both names on the card.

Keep an eye on the pace of the evening. Neither of you should be the last couple refusing to leave or the pair making a scene on the dance floor.

A short thank you note to the couple, mentioning that you and your guest had a lovely time, rounds things off beautifully. It reminds them that their generosity was noticed.

A plus-one is a privilege extended in trust. Read the invitation as written, reply promptly, prepare your guest and look after them on the day. Do that, and you will both be welcome at the next celebration.
