Men's Style Tips: Dressing for the Christmas Party in 2025

It’s party season and various Christmas events are on the cards. It’s easy to avoid making an effort and just head over in your work attire, but why not use the opportunity to make an effort and an impression? This guide covers what to wear to a Christmas party in 2025 – from formal black tie events to smart casual festive gatherings, plus advice on what socks to wear.

Christmas party season has a habit of sneaking up on you. One minute it’s a quiet December, the next you’ve got a diary full of dinners, drinks, office parties and “low-key” gatherings that are anything but.

The good news? Dressing well for a Christmas party in 2025 isn’t about novelty jumpers or last-minute panic buys. It's about getting the basics right – and then using the details to show you know what you’re doing.

Start at the feet with some great socks. Work upwards.

Formal & Black Tie Christmas Parties 

If the dress code says black tie, take it seriously – but not solemnly.

Dinner jackets, tuxedos and velvet blazers are firmly back in rotation this year, especially in deep, winter-ready tones. Black is timeless obviously, but upgrade to a deep midnight blue for something modern or swap in a burgundy velvet jacket. Texture is doing the talking in 2025, which means you can keep the rest of the look clean and classic.

What socks to wear:

For formal Christmas events, LSC's ribbed Simply Sartorials are ideal. Stick to the classics with Ebony Black, or add some colour with Rich Burgundy or even Ocean. Understated and unexpected. Immaculate. Exactly as they should be. For a pattern, Spot of Style in Classic Black is made for black tie. Just ask Mr David Gandy here.

Smart & Semi-Formal Christmas Party Outfits For Men

This is the sweet spot of festive dressing – and where most of us will probably spend December.

A sharp suit, blazer and tailored trouser, a crisp shirt, good shoes. The daily uniform, right? But it’s the finishing touches that stop it feeling safe. Think rich seasonal colours, softer tailoring, and accessories that feel chosen rather than inherited. Choose from 39 colours and counting in the Simply Sartorial canon, or take your pick from our Designer pattern collection – from houndstooth checks to herringbones to spots to Argyle, pattern is a polished way to add personality.

Argyle pattern is big for 2025. So is brown. Highland Argyle socks in Chocolate Brown are a winning combo.

What socks to wear:

Blues, rich reds like Ruby and Burgundy, sophisticated browns, earthy greens like British Racing Green and Olive – colours that sit comfortably with tailoring but still add interest. A subtle pattern like Shaken & Stirred or Highland Argyle doesn’t hurt either. Consider this the grown-up way to do festive flair.

Smart Casual & Festive Social Gatherings (What Should Men Wear?)

If it's more a 'come as you are' type event and your Christmas party is going to be more Nandos than Nobu, it's about balance. The right socks can transform a more casual outfit too and take your jeans from day-to-day to dapper. Grab the tailored trousers or dark denim, add a quality knit, and great jacket and elevate it all with some really great socks in colours that make you feel confident.

What socks to wear:

Enjoy yourself. Bold colours, confident patterns, a flash of personality at the ankle. If people notice your socks, you’re doing it right. The Block Collection by celebrity stylist Michael Fisher is a great way to play with colour.

Men’s Festive Style Trends for 2025

A few things worth knowing before you get dressed:

Texture leads the way: Velvet, brushed wool, tweed and heavier knits are everywhere

Heritage tones rule: Burgundy, forest green, navy and chocolate brown

Details count: Socks are no longer an afterthought – they’re a finishing move

Ultimately, your Christmas party is your opportunity to show off some of your personality at work. So, dressed up or dressed down, I would recommend picking a colour or pattern that makes you feel great. Then, no matter what, you won’t just be walking brighter, you’ll hopefully be dancing brighter too.
