The Ultimate Guide to Christmas Party Menswear

One of the major festive conundrums involves choosing office Christmas party outfits for men.  There are so many things to consider; What’s the dress code? Should I wear a tie? Can I get away with denim jeans?

At House of Cavani, the key to finding the perfect office party attire for men is to match your look to the formality while having plenty of festive fun. Whether you opt for a smart-casual look with a blazer, chinos or dark jeans, and a sharp shirt, or up the formality with a well-fitted suit, festive tie and decorative cufflinks, you’ll want to look your best for the occasion.

The aim should be to elevate your usual office dress to appear more festive and fun whilst remaining appropriate for the setting. From relaxed gatherings with friends to formal galas, the festive season demands a blend of smart, casual and everything in between. So, without further ado, discover our best office Christmas party outfits for men.

 

Festive office party attire for men

Christmas parties are different for everyone. For some, it’s a casual round of drinks at your local pub. For others, it’s an elegant three-course meal finished with a city skyline view. 

Whatever your Christmas party plans are this year, you’ll want to look the part. That means following the dress code and paying attention to the small detail. If you haven’t been given a dress code, make sure you check it out for added peace of mind.
 
Here at House of Cavani, we know the importance of looking your best, and that’s why we’ve broken down each dress code, so you can turn up confidently and avoid looking under or overdressed in the perfect office Christmas party outfit.

Casual office party attire for men

A night of festive drinks with your favourite colleagues is coming, and the dress code is casual. This relaxed approach voids all fears of appearing underdressed, and opens a realm of fashion possibilities, including  your favourite t-shirts and trainers.
 
If you’re heading to an evening pub, opt for darker jeans alongside a stylish polo shirt to create a stylish look. Although you should prioritise comfort, avoid wearing dress-down items such as joggers, caps and hoodies. 

Can you wear jeans to a Christmas party?

Yes, denim jeans are a viable option for an office Christmas party outfit for men. Smart-casual fits balance the line of chic and relaxed and allow you to experiment with the rest of your look.
 
The beauty of jeans is they go with almost anything. You can blend black denim jeans with a crisp white buttoned shirt for contrast, or style them with an oversized t-shirt to create an ultra-relaxed vibe. They are two completely different looks, but both require a stylish pair of denim jeans.
 
For a notch up in formality, men’s chinos provide a well-suited, semi-casual look for your festive celebrations. However, when the dress code is formal,  avoid wearing jeans, which are widely seen as inappropriate attire for these events. 

What can you wear with a Christmas jumper?

There’s only one time of year when you can make the most of your Christmas jumper, so if you decide to wear it to your office Christmas party, styling it with a pair of denim jeans will leave you both comfortable and on-trend.

But you do have to ask yourself whether or not this is appropriate. After all, turning up to a black-tie gala ball in a Christmas jumper is likely to backfire.

Smart-casual office Christmas party outfits for men

The combination of business and casual brings us to smart-casual, providing you with a traditional look that adds a touch of formality to any laid-back approach. 

If you’re preparing for a festive celebration, smart-casual is a polished yet relaxed style that blends neat, well-fitted clothing with informal elements, creating an outfit that looks professional without feeling stuffy. However, the definition isn’t concrete, but a smart-casual outfit typically involves a slim-fit blazer, brown loafers, fitted chinos and a crisp shirt. 

What’s the difference between smart-casual and casual? 

Casual wear is relaxed and informal with minimal styling, while smart-casual adds more polished, structured pieces to creating a look that’s still comfortable but noticeably more refined. So instead of wearing a t-shirt, switch it up with a classic button-down shirt.

A clearer way to think about smart-casual is to frame it with professionalism. It leans towards a corporate approach, steering clear of baggy trousers and basic t-shirts yet stopping short of formal wear.

To create the ideal smart-casual look for your office Christmas party outfit, pair your favourite casual pieces with elevated items such as tailored blazers and polished shoes. This balance keeps your outfit relaxed but refined and is one of the most versatile options as office party attire for men.

Formal office Christmas party outfits for men

When the invitation says the dress code is ‘formal’, it’s time to put on your best men’s suit. Sometimes referred to as “black tie attire”, the formal dress code is all about glamour and sophistication. 

Your upcoming Christmas party may require a classic tuxedo paired with a dress shirt, bow tie and black patent leather shoes. If the evening is more relaxed,  you can open yourself up to the world of suit options, from traditional navy suits to classic tweet suits made from heavier winter fabrics. If you’re looking for a safe option, black, blue and grey are the most common suit colours – all of which you’ll find among the House of Cavani collection.
 
When it comes to formal Christmas party styling, it ultimately depends on your preference, whether you’re looking for a slim or regular fit or a particular colour.

Should I get a two-piece or a three-piece suit? 

As the drinks flow and you shuffle towards the dance floor, you may want to take an added layer of clothing off. If this is the case, then two-piece suits are your ideal choice, coming without the waistcoat, but keeping your look intact.

Three-piece suits also have their advantages, providing an extra layer of sophistication – a matching waistcoat. Here at Cavani, we have an array of three-piece suits available in different colours and patterns, so you can feel confident in a suit you love.

Should I wear a suit to the Christmas party?

Whether or not you should wear a suit to the Christmas party all comes down to the dress code. If the occasion is formal, we recommend you bring out your favourite suit or make the investment to avoid feeling underdressed. 

If the dress code is anything below formal or semi-formal, set aside the suit for now and save it for the next suit-worthy occasion.

What suit should I wear to a Christmas party? 

These events often require a traditional tuxedo, a complementary suit that offers a pleasing silhouette with a traditional satin lapel and buttons. Paired with an elegant black bow tie or traditional neck tie, this look is the pinnacle of formal attire and one of the most noticeable office Christmas party outfits for men.

What tie should I wear at a Christmas party? 

If the dress code is formal, you need a tie, so we’ll take you through what you need to consider when selecting your tie for the Christmas party.
 
Here at Cavani, we have an array of ties available in an abundance of colours. That being said, you want your tie to complement your look. When establishing your tie choice, the fundamental rule is to go for a darker colour than your shirt. Alternatively, a patterned tie will draw attention, and a knitted tie is more minimalistic.
