Christmas Party Outfits for Men: What to Wear to Every Holiday Event
"Christmas party" can mean almost anything. It might be drinks with colleagues straight after work, a relaxed dinner with friends, a cocktail evening in a hotel bar, or a black-tie gala. The same outfit cannot work for all of them, which is why so many men arrive either overdressed or underdressed.
The short answer: for an office Christmas party, wear a navy or charcoal suit, or a blazer with tailored trousers. For a smart-casual dinner, choose quality knitwear with tailored trousers. For a cocktail party, wear dark tailoring in a richer colour such as burgundy or deep green. For a formal event, wear a tuxedo. On New Year's Eve, evening tailoring with a little more personality, such as velvet, works well.

Four things decide the right outfit: the dress code, the venue, the time of day and how formal the hosts are. This guide walks through every type of holiday event, with outfits for each.
What Should a Man Wear to a Christmas Party? The Quick Guide
| Event | Dress code | What to wear | Shoes |
|---|---|---|---|
| Office Christmas party | Business or smart | Navy or charcoal suit, or a blazer with tailored trousers | Oxfords, derbies or loafers |
| Smart-casual dinner | Smart casual | Knitwear with tailored trousers, or knitwear under a blazer | Loafers or suede shoes |
| Cocktail party | Cocktail | Dark suit or evening jacket in burgundy, green or black | Polished loafers or oxfords |
| Formal gala | Black tie | Tuxedo, white dress shirt, black bow tie | Black patent or polished oxfords |
| New Year's Eve | Cocktail to black tie | Velvet or black evening tailoring | Black loafers or oxfords |
If the invitation does not state a dress code, dress one level above what you expect. It is easy to remove a tie or open a jacket; it is impossible to make a jumper look like a suit.
What Should You Wear to an Office Christmas Party?
The office party is the event most men search for, and the one with the most at stake. You are still among colleagues and managers, so the goal is to look festive and relaxed without looking like you forgot where you were.
The safe choice: a navy or charcoal suit
A well-fitted navy or charcoal suit is always right. To shift it from a working day to a party, change the details rather than the suit. Swap your white business shirt for a deeper shade, lose the tie or choose one in a richer colour and texture, and wear loafers instead of your everyday oxfords. For ideas, see our navy suit combinations guide.
The festive choice: burgundy or deep green tailoring
If your office culture allows it, a suit in a seasonal colour is the easiest way to stand out for the right reasons. Burgundy and deep green feel festive without novelty, and both look expensive under evening lighting. A burgundy slim-fit suit or a forest green double-breasted suit works with a crisp white shirt and black shoes, and still looks appropriate in front of a manager.
The flexible choice: blazer and tailored trousers
A blazer with contrast trousers sits between business and smart casual, which makes it ideal when the party starts at the office and moves to a bar. A burgundy blazer with charcoal trousers, or a dark green blazer with grey trousers, looks deliberate and seasonal.
Do you need a tie?
Usually not. Most office parties are more relaxed than a normal working day. Wear a tie if your workplace is formal or the party is at a smart venue, and choose silk in a deep colour such as burgundy. Otherwise, an open collar with a well-fitted jacket looks confident and current.
Festive, not costume
Leave the novelty jumpers, flashing ties and Santa accessories for the family gathering. At work, festive means seasonal colour, richer textures and good tailoring, not a joke you have to wear all night.
What to Wear to a Smart-Casual Christmas Dinner
Dinners with friends and family, or relaxed restaurant bookings, call for smart casual. Knitwear is your strongest tool here: it is warm, seasonal and looks polished without trying too hard. If you are unsure where the smart-casual line sits, read What Is Smart Casual? A Simple Guide for Men.
Cable-knit jumper with tailored trousers: a cream, navy or charcoal cable knit with grey or dark trousers is the classic winter dinner outfit. See our cable-knit sweaters.
Knitwear under a blazer: a fine-gauge jumper under a blazer is smarter than knitwear alone and warmer than a shirt.
Mock-neck under tailoring: a burgundy mock-neck sweater under a charcoal or navy jacket replaces the shirt and tie entirely, and looks sharp at evening events.
Tonal dressing: shades of one colour, such as navy knit, navy blazer and grey trousers, look considered with almost no effort.
Finish with loafers or suede shoes rather than trainers. Footwear is where smart casual most often slips into plain casual.

What Should You Wear to a Christmas Cocktail Party?
Cocktail parties are where holiday dressing gets interesting. They happen in the evening, usually at a bar, hotel or private home, and they reward richer colour and texture.
Burgundy evening tailoring: a burgundy textured mono-collar jacket with black trousers is modern, festive and made for low lighting.
Deep green suits: an emerald or forest green suit with a white shirt and black shoes looks confident without being loud.
Black-on-black: a black suit with a black or dark shirt creates a sleek evening look that suits a cocktail bar well.
Three-piece suits: a waistcoat adds formality and still looks sharp once you take the jacket off later in the evening.
Keep daytime details out of evening outfits. A light blue business shirt and a striped office tie make a cocktail outfit look like you came straight from work, even when you did.
What to Wear to a Formal Christmas Party or Gala
When the invitation says black tie, there is only one answer: a tuxedo or dinner jacket, a white dress shirt, a black bow tie and black formal shoes. Our Black Tie & Gala Collection covers the essentials.
Black tie has precise rules on lapels, shirts, trousers and accessories. Rather than repeat them here, see Black Tie Decoded for the complete guide.
What Should Men Wear on New Year's Eve?
New Year's Eve is the one night of the season when a little drama is welcome. Most parties sit between cocktail and black tie, and the mood is celebratory rather than corporate, so you can dress more boldly than you would at the office party.
A velvet tuxedo: a black velvet three-piece tuxedo is the most striking choice of the season. It catches the light, feels luxurious and suits a midnight celebration perfectly.
A coloured tuxedo: a green tuxedo or burgundy evening suit keeps formal structure while adding personality.
Monochrome black: a black suit, black shirt and black loafers is sleek, modern and very hard to get wrong.
What Are the Best Colours for a Men's Christmas Party Outfit?
Burgundy and wine: the defining colour of the season. It is warm, rich and flatters most skin tones, particularly under evening lighting.
Forest and emerald green: deep greens feel seasonal without being obvious and pair well with white shirts and black shoes.
Black: the most formal colour and the natural choice for evening, gala and New Year's Eve events.
Navy: the safest colour for office parties. Lift it with a richer tie, shirt or knit.
Charcoal: serious and versatile, and a perfect base for burgundy or green accessories.
A good rule is one statement colour per outfit. A burgundy suit with a white shirt looks polished; a burgundy suit with a green shirt and a patterned tie looks like a costume.
Should You Wear Velvet to a Christmas Party?
Yes, velvet is the defining evening fabric of the season, but it belongs in the evening. Its soft sheen looks rich under candlelight and flat under office strip lighting, so save it for cocktail parties, galas and New Year's Eve.
Use velvet in one of three ways. At the top end, a velvet tuxedo is a full evening statement. In the middle, a tuxedo with velvet lapels or collar details adds texture without committing to a full velvet look. For smart-casual events, a velvet-blend knit polo gives a subtle touch of luxury, such as our pine green silk and velvet-blend polo worn under a blazer. Wear one velvet piece at a time: velvet on velvet rarely works.
Want Something Made Specifically for Your Event?
Sometimes the outfit you have in mind simply is not available ready-made, such as a velvet dinner jacket in a particular colour, a burgundy three-piece in your exact size, or tailoring for a frame outside standard sizing. Our custom-made service lets you choose the fabric, design and details with our team, made to your measurements.
Plan for at least four weeks from consultation to delivery. Count back from the date of your event, not from Christmas Day. For a mid-December office party, that means starting in mid-November; for an outfit to wear on 25 December 2026, start no later than 27 November. Earlier is always better, as delivery times can vary by location during the holiday rush.
What Are the Most Common Christmas Party Outfit Mistakes?
- Dressing too casually for the venue: if in doubt, wear the jacket.
- Treating festive as novelty: seasonal colour and texture beat reindeer jumpers at any event outside the family home.
- Too many statement pieces: a velvet jacket, a patterned shirt and a bright tie together compete for attention.
- Poorly fitting tailoring: an expensive suit that fits badly looks worse than a modest one that fits well. Check the seven points in How Should a Suit Fit?
- Wearing daytime business outfits to evening events: change the shirt and tie at least.
- Ignoring your shoes: scuffed or casual shoes undo a strong outfit. Polished loafers or oxfords finish the look.

Frequently Asked Questions
What should a man wear to an office Christmas party?
A navy or charcoal suit, or a blazer with tailored trousers, is the safest choice. Make it festive through details rather than novelty: a deeper-coloured shirt, a burgundy or green tie, or loafers instead of business shoes. If your workplace is relaxed, a burgundy or deep green suit is a stylish seasonal alternative.
Can men wear velvet to a Christmas party?
Yes. Velvet is ideal for evening Christmas parties, cocktail events and New Year's Eve, where its sheen catches the light. Wear one velvet piece per outfit, such as a velvet tuxedo or a velvet-collar tuxedo. Avoid velvet at daytime or office events, where it can look out of place.
What colours are best for a men's Christmas party outfit?
Burgundy, deep green, black, navy and charcoal are the strongest colours. Burgundy and green feel festive without looking like costume, black suits evening and formal events, and navy and charcoal are the safest for office parties. Stick to one statement colour per outfit and keep the rest neutral.
Can you wear a turtleneck or mock neck with a suit to a Christmas party?
Yes. A fine-knit turtleneck or mock neck under a suit or blazer is a sharp, modern alternative to a shirt and tie, and works well at cocktail parties and smart-casual dinners. Choose a thin knit so the jacket still sits cleanly, in black, navy or burgundy.
How early should I order a custom-made suit for Christmas?
Allow at least four weeks from consultation to delivery, and count back from the date of your event rather than from Christmas Day. For a mid-December party, start by mid-November. For Christmas Day itself, start no later than 27 November. Ordering earlier gives extra room for holiday delivery delays.
