Men’s Christmas Party Outfits: What to Wear to Every Invitation

Words by Tony Wilkes

9th November 2026


Your party invites are already arriving. And inevitably, they’ll have to be deciphered: black tie, cocktail dress, and what about the hardest of all – the work Christmas party? In short, black tie requires a tuxedo. Cocktail attire is essentially a suit styled more casually than formal eveningwear. And for the work Christmas party, opt for a more polished version of your office attire. To help you navigate any eventuality, here are five festive outfit ideas for every kind of party in your calendar.

Black Tie and the Festive Gala

A black-tie dress code demands a tuxedo. Clean, sophisticated and classic, the tux, shirt and bow tie combo have hardly changed for more than a century. A case in point, Brunello Cucinelli’s navy option has the traditional shape, with a luxurious velvet dinner jacket that will beautifully catch the light. On your feet, opt for polished Oxford shoes or loafers – just make sure they match the colour of your tux – although if you choose a white tuxedo, shoes should be black.  

The Work Christmas Party

What to wear to your work Christmas party? The answer lies in your office wear – you want to wear a smarter version of this. If, like most of us, your workplace is casual, best to choose a pair of tailored trousers styled with a smart knit. A classic, tailored jacket or overcoat can be worn over the top. If your office dress is usually a formal suit, then wear the same with some added festive touches. That might be colourful jewel tones, rich velvet or playful cufflinks. Since it’s a party, you can forgo the tie.   

Cocktail Attire

We’ve said that cocktail attire is a suit styled more casually than formal eveningwear. So what exactly does that look like? First is a suit that feels special – not the kind you’d wear ordinarily. This Rick Owens option is a good example – its overall cut and the shape of the lapels are unusual and striking. Then an easy way to complete the look is to wear a shirt or knit in a matching colour, in a fabric that’s also special – think velvets, satins or silks. Suede loafers or Chelsea boots are ideal for your footwear.  

New Year’s Eve

The dress code for New Year’s Eve may be black tie, cocktail or a casual party with friends – all of which we’ve covered separately. If, however, this is not spelled out and you have room for choice, let us present to you: the party shirt. After all, this night only comes around once a year. This is your chance to wear a confident pattern, colour or texture. Kartik Research offers some of our favourites, which are set apart by Indian fabrics and hand-done embroidery. The key is to keep your trousers and outerwear plain. It's best to let the shirt do the talking.  

Friendsmas and Casual Drinks

The way to make your casual wear festive and party-ready? Dial it up. Take this look, for example: smart tailored trousers from Dries Van Noten – featuring a cool, folded detail at the waist – paired with a printed Amiri jacket as a showstopper. It’s best to limit the ornate pieces to just one item, such as a jacket, a shirt, or embellished jeans, while keeping the rest of your outfit pared-back and plain. On your feet, pull out all the stops with a fresh pair of trainers or boots.  

Frequently Asked Questions

Not at all. For black-tie, cocktail and certain work parties, a suit is the foundation of the outfit. The key lies in how to style it. Our Harrods stylists have shared their guides to each dress code above.  

Cocktail attire for men is essentially a suit styled more casually than formal eveningwear. The suit should feel distinct from your everyday wardrobe, whether in its cut, detailing or fabric. We recommend pairing it with a shirt or knit in a matching colour in a fabric that’s also special, such as velvet, satin or silk. 

It entirely depends on your normal work attire. If your office dress code is casual, then you can absolutely wear jeans to the office Christmas party. These should be smart, however. Not ripped or embellished and dressed up with a smart jacket and polished loafers or boots.
