47 Groomsmen Proposal Messages for a Mate, a Brother and a Best Man

For your closest friend, the one who already knows

I asked my friend Kester to be a groomsman in Keswick in March 2019, on a walk that was meant to be dry. It rained from the car park. He lent me his spare waterproof, which was too short in the arms, and I asked him somewhere near the pencil museum while we were both looking at a flooded path and pretending it might clear. He said yes before I had finished, then asked what it would cost him, which was the right question and the one my card should have answered. The card I sent him a week later named the date, the town, and that I would cover his suit hire. He kept that card. The lesson stuck: a close friend does not need selling on the friendship. He needs the facts, said early, and one specific reason that is his and nobody else's.

Keep these lines personal in a way a group chat cannot copy. Name the lift home, the spare room, the year he talked you out of a bad haircut or into a good job application. If a line could be sent to three different friends without changing a word, it is not ready yet. Swap in the detail only he will recognise, even if it makes the line a bit less neat.

• You have been my first phone call in every bad month since we were seventeen. I am getting married on 14 June in Ambleside, and I need that same person standing next to me. Will you be my groomsman?
• Kester, you drove four hours to help me move a sofa up two flights of stairs and never mentioned it again. Stand with me when I get married and I will finally call us even. Will you be my groomsman?
• We have survived school, first jobs, one terrible shared flat and my cooking in 2016. I would like us to survive my wedding day together as well. Will you be my groomsman?
• You knew my partner was the one before I did, and you were polite enough not to say so for a whole month. I want you there when it becomes official. Will you be my groomsman?
• I am not asking the whole group chat. I am asking you, because you are the friend I call when the car breaks and when the news is good. Will you be my groomsman?
• There is a short list of people whose opinion I trust about suits, speeches and when to stop talking. You are at the top of it. Will you be my groomsman?
• You have seen me nervous before exams, interviews and one very ambitious soufflé. This time the nerves are happy ones. Will you be my groomsman on 9 May?
• My wedding plan has exactly one non-negotiable item so far, and it is you in the photographs looking less surprised than I will. Will you be my groomsman?
• We said at sixteen that we would be there for the big days, mostly meaning driving tests. This is the biggest one I have got. Will you be my groomsman?

For your best man, ask him separately

Ask the best man on his own, before the group hears anything. He is being handed work as well as honour: a speech, a stag do to steer, rings to hold, a groom to get to the venue washed and on time. A card that only jokes about the speech undersells that. Name one job you trust him with and say you will help with the rest, or pay for the bits that cost money. If he has a fear of public speaking, say so plainly in the card and offer the shorter toast or a reading instead. Several men say yes to the role and quietly dread one part of it for a year.

Do not ask two people to be joint best men in one card sent to both. Ask each one himself, with his own reason, and let him answer without an audience.

• I have one best man in mind and it has always been you. You kept me calm the night before my finals and you tell me the truth when I need it. Will you be my best man?
• The speech is yours if you want it, and it can be four honest minutes rather than a comedy set. I am asking you to be my best man because I trust your judgement, not your jokes.
• You organised my twenty-first, my house move and my rescue from a locked station car park. I can think of nobody safer to hold the rings. Will you be my best man?
• I need a best man who will tell me if my tie is crooked and if my speech is too long. You have never once spared me either kind of news. Will you do it?
• Being my best man comes with a suit fitting, a short speech if you want it, and me covering the hotel for the night before. The honour is real and so is the help. Will you be my best man?
• You have been the steady one in every version of my life so far. I would like you standing closest on the day it changes again. Will you be my best man?
• I asked my partner who she thought I would pick and she said your name before I opened my mouth. She was right. Will you be my best man?

For your brother, who has known you longest

A brother does not need a case made for the relationship. He was there for the childhood evidence. What lands with a brother is a line that admits the history without turning the card into a roast, and a clear word on what his partner and children are invited to, because brothers often have a household to plan around now. If you were not close for a few years and are closer now, a short honest line about that beats a card that pretends you were always inseparable. Brothers can spot that pretence in one sentence.

Skip the jokes about him being the spare or the understudy. They read worse in print than they sound in a kitchen.

• You have known me since I had a bowl cut and strong opinions about breakfast cereal. I would not get married without my brother beside me. Will you be my groomsman?
• We did not talk much in our twenties and I am glad that changed. I want you there for this, properly there, not just in the family row. Will you be my groomsman?
• You taught me to tie a tie badly in 2009 and I have been doing it your way ever since. Stand next to me on 22 August and check the knot. Will you be my groomsman?
• Mum will cry either way, so we may as well give her the photograph she has been planning since we were small. Will you be my groomsman, brother?
• You are the only person alive who remembers what I was like before I became presentable. That history earns you a place at the front. Will you be my groomsman?
• Your kids are invited, the date is 3 October, and I will sort your suit hire with mine. All I need from you is a yes and a steady hand on the morning. Will you be my groomsman?
• I have a best man, and I have friends coming, but there is a space that only a brother fills. It has your name on it. Will you be my groomsman?

For a brother-in-law or your partner's brother

This ask carries a different weight. You are not just filling a suit, you are telling your partner's family that their person matters to you in his own right, not as a polite extra. Keep the line warm and specific about him, not about how happy it will make his sister or his parents. If you barely know him yet, do not fake a long history. Name the one real thing you have shared, a match, a lift, a Sunday lunch where he made you laugh, and say you would like to know him better. That honesty reads well and it gives him an easy yes.

Tell him early what the other groomsmen are like, in one line, so he is not walking into a room of strangers at the fitting.

• I know we met through my partner, but I am asking you because of you: you made her whole family feel easy to join. Will you be my groomsman?
• You gave me the honest tour of this family at Christmas, including who to sit next to and who to avoid after pudding. I owe you for that. Will you be my groomsman?
• We have only watched football together twice and argued about one referee for most of it. I would still rather have you beside me than most people I have known for years. Will you be my groomsman?
• Your sister says you are the calm one, which is exactly what a wedding morning needs and exactly what I am not. Will you be my groomsman?
• I am not asking to be polite to your family. I am asking because I like you and I trust you, and I would like us to be brothers in more than paperwork. Will you be my groomsman?
• The fitting is in town, I will cover the hire, and the other groomsmen are a friendly lot who will argue about playlists, not much else. Will you be my groomsman?

Funny ones, if you can say them out loud without wincing

Humour works in these cards when it punches at you, the groom, or at the formalwear. It fails when it punches at the man you are asking, his dancing, his hairline, his past relationships. Read each line aloud before you write it. If you would not say it to his face in a pub, it does not belong in a card he may keep for twenty years. The open bar joke is in every shop-bought card in the country, so if you use a drinking joke, make it yours: name his actual order, his actual tolerance, the actual night you both still mention.

One funny line per card is enough. A card that is all jokes leaves him unsure whether you meant it. Put the joke first, then one plain sentence that you do.

• Your service as a groomsman is requested. The uniform is a suit, the hours are long, the pay is one dinner and my permanent gratitude. Will you report for duty?
• I have been promoted from wingman duties and I am allowed to recruit. You are my first pick, partly for loyalty and partly because you already own shoes that fit the dress code. Will you be my groomsman?
• This could have been a text. My partner said a text was not good enough for you, and she was right, so here is a card asking the same thing with better handwriting. Will you be my groomsman?
• Two words: matching waistcoats. I know. I am sorry. I am asking anyway, because if anyone can carry off that much pattern, it is you. Will you be my groomsman?
• I need a groomsman who can tie a Windsor knot, find a lost cufflink and look calm in photographs. You can do one of those three and that is the best offer I have had. Will you be my groomsman?
• There will be cake, a short ceremony and a dance floor where your moves from 2014 may finally get the audience they deserve. Will you be my groomsman?
• I checked and you cannot be fined for saying no to this card, worse luck for me. I am asking properly, with hope and a spare buttonhole. Will you be my groomsman?

Short ones for a gift tag, a box lid or a bottle label

Sometimes the ask rides on an object: a bottle with a label, a box lid, a tag tied to a pair of socks he will actually wear on the day. Short lines have to do two jobs in a few words, name the role and make it his. Avoid lines that only work if he opens the gift in front of you. Write it so it still makes sense when he finds the tag at midnight on his kitchen table. Keep the date off the tag and put it in a note inside, tags get thrown away and dates get forgotten, and you want the one thing he keeps to be the ask itself.

• Suit up. 14 June, Ambleside, my side. Will you be my groomsman?
• She said yes. Your turn. Will you be my groomsman?
• Brother in every way that counts. Stand with me. Will you be my groomsman?
• Rings, speech, steady hand. I pick you. Will you be my best man?
• One job, one suit, one old friend. Will you be my groomsman?
• For the man who has never let me down. Will you be my groomsman?

When you are asking late, from far away, or after a change

Life produces these asks. Someone moves abroad, a friendship deepens late, a groomsman has to step back because of a baby, an illness or money, and you need to ask another man without making him feel like a substitute. Be straight about the timing in the card. Do not invent a story about always meaning to ask him this month. Name the change in one sentence, without sharing the other man's private reasons, then make the ask on its own merits. A man asked late who is told the truth usually says yes with more warmth than a man who smells a cover story.

If he lives far away, put the travel facts in the card: what you will cover, where he can stay, which parts he can skip. A groomsman who lives overseas does not need to attend every fitting and every pub night to earn the title. Say that, and mean it.

• I am asking late and I will not dress that up. Our friendship grew this year in a way I did not expect, and I want you there. Will you be my groomsman?
• One of my groomsmen has had to step back for family reasons that are his to share. I am not asking you as a replacement. I am asking because I should have asked you in the first round. Will you be my groomsman?
• You live a nine-hour flight away, so here is the deal in writing: I cover your hotel for two nights, you skip the fittings, you arrive for the rehearsal dinner. Will you be my groomsman?
• We have mostly been friends by phone and bad video calls since you moved. That has still been a real friendship, and I want it in the room on the day. Will you be my groomsman?
• The wedding is in eleven weeks, which is short notice for a suit and a speech and a life. Take a week to think, check the costs I have listed inside, and tell me honestly. Will you be my groomsman?

What not to put in the card

Leave the money surprises out by putting the money facts in. If he will need to pay for suit hire, travel, a hotel and a stag weekend, a rough total in the card or in a note with it respects him more than a cheerful ask followed by four invoices. You do not need a spreadsheet. One line, I will cover this, you will need roughly this, is enough for him to say yes with his eyes open.

Do not put the stag do plan, the suit shop deadline and a list of duties in the proposal card. That turns an honour into an admin email. Send the logistics a week later, once he has said yes and had a day to enjoy being asked. Do not ask in a group setting where saying no would embarrass him, and do not ask by group card or group chat, where the first yes pressures the rest. One person, one card, one real chance to decline. And never write that he cannot say no, even as a joke. Some men are carrying costs, caring duties or a new baby that you know nothing about, and a line that traps them will sit badly for years.

The line I have used, and meant, is the plain one: I would love you there, and I will understand if the answer is no. Saying that out loud is what got me honest answers instead of polite ones.

Finally, do not copy the wording off the box the card came in. Shop cards can carry the question, but the reason has to be yours. Two sentences in your own handwriting, even untidy ones, are worth more than a printed paragraph about brotherhood.

Turn it into a group card

Once your groomsmen have said yes, the same group usually needs a card for the couple, a thank-you for the best man, or a wedding card that does not sound like it was written by a committee in a corridor. A group card with multiple signers lets each man add his own line in his own words, which is the whole trick with groomsmen: they sound better individually than averaged. You can create a card online and send one link round the group instead of chasing photographs of handwriting.

For the wedding itself, the shipped guides to wedding card messages and what to write in a wedding card cover the couple's card when your turn comes to sign one. If the group would rather keep things digital until the day, free ecards are a simple way to send the ask and the thank-you without a postal deadline.

The reel from that flooded Keswick walk is still in a drawer at home, a brass fishing reel Kester bought for six pounds at a market stall and swore he would repair. The line tangles if you look at it. It sits next to a dead torch and a tin of buttons, and every few months I take it out, turn the handle twice, and put it back, because the shop that sold the right spring closed the year after and I have not found another. Kester asks about it sometimes. I tell him it is nearly fixed.
