Most men get the Christmas party invite and do one of two things: wear what they wore to work, or overcorrect with something they would never normally touch. Neither is right. The best Christmas party outfit for a man is a sharper version of how he already dresses: darker, more textured and with one deliberate detail. Here are seven outfits that do that, sorted by the kind of party you are going to.
First, read the invitation properly
"Smart casual" at a Christmas party means a step up from the office, not a step down. "Festive" means a colour or a texture, not a novelty jumper. "Cocktail" or "dress to impress" means a jacket. "Black tie" means a dinner suit, and nothing else counts. If the invitation says nothing, dress for the venue: a pub tolerates knitwear and dark jeans, a restaurant expects a collar or a roll neck, a hotel ballroom expects tailoring. Our UK smart casual guide covers the dress code in detail.
1. The work Christmas party: roll neck and tailored trousers
The safest sharp outfit there is. A fine slim ribbed roll neck in black or charcoal replaces the shirt and tie, stretch smart trousers handle a long evening of sitting and standing, and suede-look loafers from your wardrobe finish it. Add a longline overcoat for the journey. It reads as considered without looking like you are trying to upstage the boss. Read how to wear a roll neck jumper for fit and colour.
2. The pub Christmas drinks: textured knit and dark jeans
Pub parties are warm, crowded and informal, so the outfit needs to survive being sat on, leant against and spilt on. A cable knit jumper over a plain tee, slim black jeans and clean low-top trainers does it. The texture of the cable knit is the festive element, so keep everything else plain. If the pub is cold, a quilted gilet goes over the knit and comes off at the table.
3. The restaurant dinner: mock neck under a blazer or shawl cardigan
For a sit-down dinner where a shirt feels stiff but a jumper feels too casual, a fine knit mock neck under a dark blazer is the answer. No blazer? A shawl collar cardigan does the same job of adding a lapel and some structure, and is far more comfortable over three courses. Pair with pleated trousers or tapered trousers in charcoal or navy and loafers. Compare the two necklines in mock neck vs turtleneck. Ours is the Bedford herringbone blazer — single-breasted, with a notch lapel and patch pockets, in a cotton-blend herringbone weave.
4. The "festive dress code" party: colour in the knit, not the trousers
When the invitation asks for something festive, put the colour where it can be taken off: in the knitwear. A Nordic quarter-zip jumper with a Fair Isle band gives you the seasonal pattern without the flashing lights, and worn over an Oxford shirt with navy trousers it still looks like an outfit an adult chose. For the full case against novelty knits, read our guide to men's Fair Isle jumpers. Browse the styles in our men's Fair Isle jumpers collection.
The Highbury is true to size; if you are between sizes, size up for layering or a more relaxed fit, or down for a closer fit.
5. Black tie: the parts most men get wrong
A black tie Christmas party needs a dinner jacket, satin stripe dinner trousers, a white dress shirt and a black bow tie. The details that separate a correct outfit from a hired-looking one: braces rather than a belt, black socks long enough not to show skin when you sit, and polished black shoes. If you already own the jacket and shirt, our tailoring collection covers the rest. Our Albert pre-tied bow tie is the bow we make for it — double-layer, already tied, in black, navy, burgundy and charcoal. The braces in question are button-end, not clip-on: the Chancery braces fasten to buttons inside the waistband and hold the trouser line unbroken.
6. The house party: smart overshirt and chinos
Coats come off at the door and everyone ends up in the kitchen, so the layer you are wearing underneath is the outfit. A corduroy overshirt over a plain tee or fine knit, slim tapered chinos and clean trainers looks intentional and stays comfortable. Five more combinations in how to style a corduroy overshirt.
7. The cold-night outer layer that works with all of them
December parties mean standing outside taxis and smoking areas, so the coat matters as much as the outfit. A longline overcoat in camel or charcoal upgrades every look above, and a herringbone scarf adds the one texture that reads festive without saying so. If you want something lighter, the suede-look zip jacket works over a roll neck for restaurant and bar nights. Compare options in the men's winter coat guide. For the smarter rooms — cocktail dress codes and hotel ballrooms — a double-breasted overcoat is the sharper finish.
Five mistakes to avoid
- The novelty jumper at anything but a novelty jumper party. If the invite does not say Christmas jumper, do not wear one.
- Office shirt, office trousers, office shoes. Change at least one of the three or it looks like you forgot.
- Brand-new shoes. A Christmas party is four hours on your feet; break them in first.
- Too many statement pieces. One patterned or coloured item per outfit. The rest stays neutral.
- Light-coloured trousers. Mulled wine, gravy and crowded bars. Dark trousers forgive everything.
Frequently asked questions
What should a man wear to a Christmas party?
A sharper version of your normal smart casual: dark trousers or jeans, a fine knit (roll neck, mock neck or textured jumper) or a shirt under a knit, and clean shoes. Add one festive element, such as a Fair Isle band or a deep colour, and a good coat for the journey.
What do you wear to a work Christmas party as a man?
One step smarter than your normal office look, with nothing that could embarrass you in front of senior colleagues. A roll neck with tailored trousers and loafers, or an Oxford shirt under a quarter-zip with chinos, are both safe and look deliberate.
Can you wear jeans to a Christmas party?
Yes, for pub, house and most restaurant parties, as long as they are dark, slim or straight and free of rips. Balance them with a smarter top half. Avoid jeans for cocktail or black tie dress codes.
Can you wear trainers to a Christmas party?
Clean, minimal leather-look trainers work for pub, house and casual restaurant parties. For anything smarter, loafers or Chelsea boots are the better choice.

The evening upgrade: velvet and proper tailoring
If one piece changes a party outfit from smart to dressed, it is the jacket. Our velvet dinner jacket (£169.00) has a black satin shawl lapel and a single-button front: wear the Burgundy with a white shirt and black bow tie for the full black-tie read, or the Navy over a black roll neck and black trousers for the modern version. It completes the satin stripe dinner trousers in outfit five, and it is the strongest piece in our tailoring collection — the shelf to shop when the invitation says cocktail, dress to impress or black tie.
Shop the party edit: start with tailoring and the smart casual edit, take the knitwear from men's knitwear, and finish with the Mayfair velvet dinner jacket if the season calls for one statement piece. Free tracked UK delivery on every order — dispatch in 1–2 working days, delivery 6–10 working days from order; order by Wednesday 9 December for the party season.
