Men’s Autumn/Winter 2025 Suit Trends

As we edge into the cooler months, men’s suiting is coming to the forefront of AW trends. After a summer season of relaxed dressing and casual tailoring, the focus shifts back to sharp structure, elegant drape, and impeccable fit. This is the season of the modern gentleman: composed, confident, and classically dressed.

From wool mix fabrics and stretch blends to earthy tweeds and timeless navys, every detail this year revolves around quality, versatility, and craftsmanship. Below, we break down the key trends redefining the modern suit for the cold season ahead.

The Comeback of Wool Mix Fabrics

If there’s one fabric that defines the essence of A/W tailoring, it’s wool — but not as you’ve seen it before. Whilst full wool suits have their own place in a man's closet, there's no denying that a full wool suit is an expensive option, and one usually reserved for special occasions. That's where the more affordable wool mix option comes in. Wool mix suits are an innovative blend that combines tradition, performance and affordability.

The result of this new tailoring style is subtle sophistication. Whether it's a herringbone two-piece or rustic tweed blazer, these styles hold their structure while adapting to your lifestyle. Perfect for busy commutes, important meetings, or autumn weddings, they merge old school tailoring with modern practicality seamlessly.

The Smart Stretch: Elastane-Blend Tailoring

Comfort has become one of the most sought-after features of a modern suit. Enter elastane-blend fabrics — a quiet revolution in menswear. Suits with added elastane or Lycra, usually around 2-4%, provides an incredible difference in moving and wearability.

This new generation of fabric helps to retain a sharp silhouette while allowing for natural movement. Whether you’re reaching for your laptop or on a long commute, this fabric choice moves with you.

Elastane blends also help your suit to maintain its shape over time, resisting strain and springing back more than your traditional blends. The result? A polished look that doesn’t compromise on comfort or style.

Slim, Tailored, and Timeless

The fit of your suit defines everything. A poorly fitted suit can ruin a whole look. While the catwalks have been awash with a looser, more relaxed fit, slim tailored fit still reigns supreme thanks to its adaptability to suit the majority of frames.

Blazers feature a moderate structured shoulder for definition with a natural slope that complements the frame rather than exaggerating it. Sleeves remain traditional and fall just above the wrist bone allowing for a peek of shirt to pop through. Trousers are tapered slightly at the hem, sitting comfortably on the waist and falling neatly on the shoe, ensuring no hem sag.

It’s the kind of suit that feels custom-fitted, even off the rack. The goal: timeless confidence. A well-tailored suit doesn’t chase trends — it sets the standard.

The Season’s Colour Palette: Tweeds, Tans, Olives, and Navys

This autumn texture and tone take centre stage. While black and navy remain the anchors for seasonal dressing, earthy heritage-inspired colours are also having a moment, with styles leaning into nature's natural colour palette.

Tweed Revival: From traditional herringbone to soft check patterns, tweed makes a strong return. AW25 sees updated fabric compositions with wool mix styles offering a lighter alternative to full wool suits. Tweed is no longer just reserved for countryside wear; it’s city-ready sophistication. Style with leather boots and a chunky knit for an effortless take on this classic look.
Tan and Camel: These warm mid-tone hues add instant warmth this autumn/winter. One of the most sought-after colours this season, thanks to its easy styling versatility. A tan wool suit looks incredible layered with darker colours like olive or chocolate brown.
Olive Green: A standout shade for the last few seasons, Olive is bold without being brassy. It's a colour that flatters every skin tone and transitions from officer to vennig seamlessly. Our Bromley Olive Suit is the perfect option for those seeking to try this trend. It offers a timeless modern option suitable for a myriad of occasions.
Navy Reinvented: The perennial favourite gets a notable mention thanks to its timeless versatility. Whether it’s a classic three-piece or a checked two-piece, a navy suit is always a good investment. It’s still the most versatile colour in a man’s wardrobe, but with more character than ever.
The Black Tuxedo: A black suit is every man's go-to option when it comes to autumn/winter dressing. This season think simple, pared-down tuxedos - slim lapels, minimalist satin details and classic slim tailored cut. It’s understated elegance that never goes out of fashion.

Crafting a wardrobe of these tones will help create a versatile palette that works across formal and informal, day and night.

Layering and Finishing Touches

A well-tailored suit is just the first step. This season, we’re leaning into layering with textures at the forefront of the list. Think pieces that add warmth but also visual depth and interest, play close attention to the types of layers you are mixing, as you don't want to disrupt the line of your suit.

Ditch the shirt in favour of a fine knit rollneck jumper in charcoal, cream or khaki for a smart seasonal update. Add a classic wool overcoat with strong lapels to extend the tailored silhouette. Accessories should follow suit - think wool or knitted ties, pocket squares in autumnal tones like burnt orange, burgundy or greens. Finish with polished leather loafers, brogues or boots.

When styled right, your A/W suit can transition seamlessly from the boardroom to the bar, from weekday to weekend.
