How to actually look good at a wedding (a practical guide for men who don’t think about clothes)

Wedding season is upon us and somewhere in Britain, right now, a man is staring at his wardrobe with genuine panic. He has been invited to a wedding. The dress code says "smart" or "formal" or, worst of all, "black tie". He owns a suit. He thinks. It might still fit. He wore it to his cousin's wedding in 2019 and it was fine. Probably.

If any of that sounds familiar, this guide is for you. Not because you need to become a fashion person. Not because you need to spend a fortune. But because weddings are one of those occasions where a small amount of effort pays off disproportionately, and because the difference between looking like you tried and looking like you genuinely considered it is smaller than most men think.

First things first: actually read the dress code

This sounds obvious but it genuinely is not. Dress codes at British weddings have become increasingly creative and increasingly vague, and the gap between "smart casual", "lounge suit", and "black tie" is significant enough to get badly wrong.

Lounge suit is the most common dress code for British weddings and it means exactly what it says: a suit, worn properly. Not a blazer with chinos. An actual suit, with matching jacket and trousers, in a decent fabric, that fits you properly. This is the baseline and it is not a hard one to meet.

Black tie means a dinner suit. Dark jacket, matching trousers with a satin stripe, white dress shirt, black bow tie. If you do not own one, hiring is a perfectly reasonable option, but buying is worth considering if you have a few weddings coming up. A dinner suit that fits well is one of the most useful things a man can own.

"Smart casual" is the most treacherous dress code in existence. It means different things to different hosts and the safest interpretation is to dress as smartly as you would for a lounge suit occasion and then consider whether you can relax one element. When in doubt, overdress slightly. Nobody has ever been embarrassed by being the best-dressed person in the room.

The suit situation

If you already own a suit, the first question is whether it still fits. Bodies change, and a suit that fitted well five years ago may not fit well now. Try it on properly: jacket on, buttons done, move around. Do the shoulders sit cleanly at the edge of your actual shoulders? Does the chest close without pulling? Do the trousers sit at the waist without needing a belt yanked tight to keep them up?

If the answer to any of those questions is no, you have a decision to make. A good tailor can often rescue a suit that almost fits, and the cost of basic alterations is significantly less than buying new. If the suit is genuinely too far gone, it is worth investing in something that actually works.

If you are buying, the range of formal men's attire available at a range of price points has never been better. The key thing to look for is fit: a moderately priced suit that fits well will always look better than an expensive one that does not. Pay particular attention to the shoulders, the chest, and the trouser length. Everything else can be altered.

For a summer wedding, a lighter fabric in a mid-grey, navy, or if you are feeling adventurous, a warm tan or stone, is both more comfortable and more appropriate than heavy dark wool. For autumn and winter weddings, a slightly heavier fabric in navy or charcoal is the reliable choice.

The stuff that goes with the suit

This is where a lot of men lose marks. The suit is fine but the shirt is the one from the back of the wardrobe that has been ironed approximately once. The shoes are the black lace-ups that have been worn to every formal occasion since university and have not seen polish since approximately the same period. The tie, if there is one, is the novelty one received as a Christmas present in 2011.

The shirt matters more than most men realise. A crisp white or pale blue shirt in a proper fabric, fitted reasonably well, changes how the whole outfit reads. It does not need to be expensive. It needs to be clean, pressed, and the right size. If the collar gaps around your neck or the buttons pull across the chest, it is the wrong shirt.

Shoes are worth the effort. A clean, polished leather shoe in black or dark brown, appropriate to the formality of the occasion, makes a noticeable difference to how put-together the overall look appears. If yours have not been polished recently, polish them. It takes ten minutes and the difference is visible.

The tie question is a personal one. A tie adds formality and is generally appropriate for lounge suit weddings, though not mandatory at most. If you are wearing one, a simple, well-made tie in a solid colour or subtle pattern will serve you better than anything too loud or too jokey. This is someone's wedding, not a Christmas party.

Fit is the thing that actually matters

It is worth saying this plainly because it is the single most important factor in whether you look good or not: fit matters more than brand, more than price, and more than how nice the fabric is.

A suit that fits your specific body, with the jacket sitting cleanly on your shoulders, the chest closing without pulling, the sleeves finishing at the right point on your wrist, and the trousers breaking at the right point over your shoes, will look significantly better than a more expensive suit that does not fit those criteria.

If you are buying something new and the fit is not quite right off the rail, ask about alterations. Most menswear retailers either offer in-house tailoring or can recommend someone nearby. The cost is generally modest and the difference to how the suit looks is anything but.

A note on colour for summer weddings

British summer weddings increasingly lean towards lighter, warmer colour palettes, and a dark suit that would be perfect for a winter occasion can feel slightly heavy in strong summer light. If the wedding is outdoors, or in a bright venue, or in the height of summer, consider whether a lighter option might serve you better.

Navy remains the most versatile choice for almost any season and occasion. Mid-grey works beautifully for summer. And if you have a bit more confidence in your clothing choices, or simply want to wear something that feels a bit more personal, a warm tan, a soft olive, or a light stone can look genuinely excellent at a summer wedding and will set you apart from the sea of navy and grey in a way that requires essentially no additional effort.

The morning of: practical things worth doing

Give yourself more time than you think you need. This sounds like advice for people who are habitually late, but it applies to everyone when getting dressed for a formal occasion. Things take longer when they matter.

Check everything the night before: suit, shirt, shoes, tie if applicable. If anything needs ironing, iron it the night before rather than in a hurry on the morning. Check that your shoes are clean. Check that all the buttons are present and attached.

On the morning, dress properly and then leave it alone. The most common styling mistake at formal occasions is continued fiddling: the tie that gets adjusted every ten minutes, the jacket that comes on and off, the collar that gets tugged repeatedly. Put it on, check that it looks right, and then stop touching it. Confidence in how you look comes partly from not drawing attention to your own uncertainty about it.

The actual goal

The goal is not to look like a model or to win some kind of best-dressed competition. The goal is to look like someone who respected the occasion enough to make a genuine effort, and to feel comfortable enough in what you are wearing that you can spend the day enjoying a wedding rather than thinking about your clothes.

That is a genuinely achievable bar. And the good news is that it requires less expertise, less money, and less time than most men assume. A suit that fits, a shirt that is clean and pressed, shoes that have been polished, and a small amount of advance planning. That is genuinely most of it.
