By the end of this guide you will have agreed with your host how you are introduced, dressed for the room, and got through a gala, work event or wedding with easy conversation and nothing said that either of you would regret. You will also have left on your own terms and sent the thank-you that gets you invited again.

A plus-one has one job: make the host's evening easier. The host is there for the cause, the colleagues or the couple getting married. You are there so they arrive with someone good company, and so the people they know meet someone they like. Everything below serves that.

Know the room before you say yes

Each kind of event asks something different of a plus-one. Read the row for yours, then ask your host what the table leaves out.

	Gala or charity dinner	Work event	Wedding	Opening night
Usual dress	Black tie, sometimes white tie	Lounge suit or smart casual	As the invitation says; never white	Smart casual to black tie
Who you meet	Donors, organisers, the host's circle	The host's colleagues, clients, perhaps a boss	Family and old friends	Other guests, briefly
What the host needs	A calm partner through a long evening	Someone who never embarrasses them at work	Someone who blends in and lets the couple shine	Company, and a reason to linger at the bar after
Length	Four to six hours, seated	Two to three hours, standing	A full day or evening	Two to four hours
Hardest moment	Speeches and the auction	"And what do you do?"	"How did you two meet?"	The interval crowd

Dress codes have exact meanings. Black tie means a black dinner jacket with silk lapels, or for women usually a knee-length cocktail dress, though a floor-length gown also works. Lounge suit means business dress. Smart casual rules out even designer denim ¹. Our guide to dress codes goes venue by venue.

Before the event: agree the story

Most plus-one mistakes happen in the first thirty seconds of an introduction, and every one of them is fixed by a ten-minute conversation a few days before. Have it in your messages, not on the way in.

Ask how you will be introduced. "My partner", "my date", "a friend" and just your first name each tell the room something different. The host knows their room; let them choose, and say if a word does not sit right with you.
Agree one answer to "How did you two meet?" It will come, usually more than once. A short true answer both of you give the same way beats a clever one. "Through friends" or "online" is enough for most rooms; you never owe anyone the name of the site.
Ask who will be there and who matters. Three names are plenty: the boss, the bride's mother, the organiser. Knowing them lets you greet the right people warmly without being steered.
Ask what not to talk about. A work deal, a family feud, an ex who will be at the next table. One line from the host saves you from the one topic that ruins their night.
Confirm the dress code, times and your way home. Know when it starts, when the host expects to leave, and how you get home. Your own transport means you choose when you go ².
Settle photos and social media. Ask whether the host is happy to be photographed with you, and say whether you are. Agree that neither of you posts or tags the other without asking.

A message that covers all of it:

"Looking forward to Saturday. A few quick questions so I get it right: how would you like to introduce me, and what shall we say if someone asks how we met? Who should I make a point of meeting, and is there anything I should steer clear of? Also, black tie, 7 till about 11? I'll book my own car home."

If you are going through the Board, an event listing often reads "plus one" in the title. The venue name is shown only to the accepted guest, and the private conversation opens once the host accepts you, so this is the first message to send after you confirm. Accepting and confirming walks through the steps.

Arrival and introductions

Arrive together, or meet just outside. Walking in separately and finding each other in a crowded room looks awkward and wastes the host's first ten minutes.
Let the host lead the first introductions. Stand beside them, not behind. When they say your name, offer your hand, make eye contact and repeat the other person's name once.
Use the other person's name once more when you part. It fixes it in your memory, and people notice being remembered.
Introduce yourself when the host is pulled away. They will be. A first name and your link to the host is all you need.
Introduce others when you can. If you have just met two people standing alone, bring them together. It makes you the easiest guest in the room, which reflects on your host.

When your host is called away:

"Hello, I'm Sam. I'm here with Alex. How do you know the couple?"

When you have forgotten a name:

"I'm so sorry, it's been a night of new names. Remind me yours?"

When you are handing someone on:

"Have you two met? Jo, this is Priya, she's just back from Tokyo. Priya, Jo is on the gala committee."

Conversation that carries the evening

You do not need to be interesting. You need to be interested. People at these events talk about themselves all night, and the guest who asks the second question is the one they remember.

Ask about the event, not the person's money or job title. "How did you get involved with the charity?" opens more than "What do you do?" and never sounds like sizing someone up.
Ask the follow-up. Listen to the answer, then ask about the part they sounded keen on. Good communication is saying clearly what you mean and listening carefully to the reply ³.
Keep a few safe topics ready. The venue, the food, travel, a book or film, what they are doing next weekend. Skip politics, religion and anyone's salary.
Have a short answer about yourself. One line about your work or study and one about something you enjoy. Then turn it back to them.
Stay out of the host's business. At a work event you may hear about deals, clients or colleagues. Nod, do not add, and never repeat it later.
Check in with the host now and then. A glance across the room, a hand on the arm, a quick "All good?" tells them you are with them, and gives either of you a moment to signal it is time to go.

When someone presses on how you met:

"Through friends, really. Alex, you tell it better."

When someone asks what you do and you would rather keep it light:

"I'm in marketing, which mostly means too many meetings. What about you? How do you know the bride?"

When a question goes too far:

"Oh, that's a story for another night. Have you tried the oysters?"

Discretion: what stays at the event

Discretion is the quality hosts value most in a plus-one, and it runs both ways. You protect their privacy; you also protect your own.

Never post the host, their colleagues or their family. Not a photo, a check-in or a tag, unless the host has said yes to that exact post.
Stay out of the event photographer's official shots unless the host asks. At galas and weddings, photos end up on websites and in albums. Step aside with a smile.
Keep what you hear to yourself. Family news at a wedding, a restructure at a work party: none of it is yours to share.
Keep your own details light. Your first name is enough. Police advice for meeting anyone from online is to keep your surname, home address and workplace to yourself until you trust the person ⁴. That holds for their friends too.
Never discuss your arrangement in the room. Whatever you and the host have agreed is between you. If anyone asks, the agreed answer to "how did you meet" is the whole answer.

Our guide to protecting your privacy covers photos, social media and separate contact details in full.

At the table

Galas and weddings are usually seated dinners, often with strangers either side of you. A few old rules carry you through.

Talk to the people on both sides. Not just your host. A plus-one who leaves the neighbour on their other side staring at the centrepiece is noticed.
Wait until everyone is served before you start, unless the host of the table says otherwise. Offer dishes to others before serving yourself, and never stretch across people ⁵.
Stay put through the speeches. Phone away, glass down, eyes on whoever is speaking. Leaving the table during a toast is the one thing a wedding remembers.
Leave the auction to your host. At charity dinners, never bid, and never nudge your host to.

For cutlery, wine and bread plates, see fine dining etiquette.

Drinks: pace yourself

Long events come with a lot of free drink, and the plus-one who stays sharp is the one invited back.

Match or stay under your host. Never finish the night more relaxed than the person who brought you, especially at their work.
Alternate with water. Take one every time you take a glass of wine.
Keep your drink in sight. Hold it, or finish it before you go to the dance floor. Do not keep drinking a drink you left unattended ².

Leaving well

Leave when you agreed, or together. If you need to go earlier, tell your host quietly first, never by text from the taxi.
Thank the people who looked after you. The couple, the organiser, whoever sat beside you. A sentence each.
Go home your own way if that was the plan. An invitation to an after-party, a hotel room or the host's home is a new question, and you can say no. You do not owe anyone anything because they paid for your evening ².
Send a thank-you the next day. One specific memory from the evening does more than any compliment.

Saying no at the door:

"Thank you, tonight was lovely. I'm heading home, my car's here. Talk tomorrow."

The thank-you the next day:

"Thank you for last night. Your sister's speech had the whole room in tears, and I loved meeting Jo. I'd happily do it again."

If you met through the Board, each of you may leave a private rating after the date. Ratings are never public. Pressing "would meet again" is the clearest compliment you can pay a host.

If you are the host

A great plus-one needs a good host. Give your guest what you would want walking into a room full of strangers.

Brief them a few days before: who, what to wear, what not to raise, and the one-line answer to "how did you meet".
Introduce them to everyone you stop to talk to, by first name and with something to talk about.
Do not leave them alone for more than a few minutes early on. Later, they will find their feet.
Say plainly what you are covering, and never ask your guest to pay anything back. The Board refuses listings that ask a guest to pay or deposit money.
Let them leave when they want to, with no fuss.

Writing an invitation for an event? Posting an invitation shows how to describe the occasion, the dress code and what you provide, so the right guest applies.

Questions people ask

What does a plus-one do at a wedding?

A wedding plus-one keeps their host company, blends in, and lets the couple shine. Dress as the invitation says and never in white. Greet the family your host points out, talk to the people either side of you at dinner, stay seated through the speeches, and stay off social media unless the couple has asked for posts. Thank the couple before you leave.

How should a plus-one introduce themselves?

Give your first name and your link to the host: "Hello, I'm Sam, I'm here with Alex." Then ask a question about the event, such as how they know the couple or how they got involved with the charity. Agree beforehand how the host will introduce you, whether as a partner, a date or a friend, so you both say the same thing.

What do you say when someone asks how you met your date?

Agree one short, true answer with your host before the event and both give it the same way. "Through friends" or "online" is enough for almost any room. You never owe anyone the name of the site or the details of your arrangement. If someone keeps pressing, smile, say it is a story for another night, and change the subject.

How do you behave as a plus-one at a work event?

Remember it is your host's workplace. Dress as their colleagues will, drink less than your host, and let them lead introductions. Ask colleagues about the event and themselves rather than their jobs or salaries. Anything you overhear about deals, clients or restructures stays at the event. Leave together or when agreed, and thank whoever organised it.

Should a plus-one bring a gift to a wedding?

Ask your host. Usually the invited guest gives the gift, sometimes from both of you, and a plus-one does not need to bring a separate one. If your host would like it to come from both of you, offer to write the card. A handwritten thank-you to the couple afterwards is always welcome and costs nothing.

What should a plus-one wear to a black tie gala?

Black tie means a black dinner jacket with silk lapels for men. For women it usually means a knee-length cocktail dress, though a floor-length gown also works. Check the invitation and ask your host, because some galas are white tie, the most formal code, which calls for a tailcoat or a full-length evening gown.

Do I have to go home with my date after an event?

No. An invitation to an event is an invitation to that event and nothing else. A ticket, a dress or a flight does not buy anything more. Book your own way home before you go so you choose when you leave. If anyone pressures you after you say no, leave, and report them if you met through a dating site.
