Spring/Summer 2026 Men's Fashion Essentials and Trends
The warmer months are back, and with them a fresh take on what it means to dress well in the heat. Spring/summer 2026 keeps the easy, sun-drenched spirit we've loved for a few seasons now – think Riviera mornings, garden parties and long weddings that drift into the evening – but the tailoring underneath has quietly evolved. Fits are softer, colours are warmer, and the whole mood leans towards comfort that still looks considered.
Below, we break down the essentials worth investing in this season, the trends shaping menswear right now, and how to pull it all together – whether you're a wedding guest, a groom, or simply after a sharper summer wardrobe. As always, every piece we suggest is something you'll find in our men's collection, made to look good and last well beyond one summer.

Spring/summer 2026 colour story: pastels meet earthy neutrals
First, pastels are firmly back – soft, washed-through shades rather than anything garish. Lilac, powder blue, mint green, baby pink and pale yellow all feel fresh and photograph beautifully outdoors, which makes them a natural fit for garden weddings and daytime celebrations.
Second, and arguably the bigger story, are earthy neutrals. Stone, sand, sage, camel, tan and chocolate brown have moved from quiet alternative to genuine front-runner. They're flattering on most complexions, easy to mix, and they read as effortlessly expensive in natural light.
The easiest way to wear either: keep the silhouette simple and let the colour do the talking. A tonal outfit – one shade carried across jacket, shirt and trousers – looks deliberate and modern without much effort.
Luxe linen and the rise of relaxed tailoring in spring/summer 2026
If there's one fabric that defines the season, it's linen. A good linen blazer or linen suit is the cornerstone of a summer wardrobe – breathable, lightweight and made for standing, moving and dancing through a long, warm day.
What's changed for spring/summer 2026 is the cut. The sculpted, slim-to-the-body suit has given way to relaxed tailoring: softer shoulders, lighter (often half-lined or unlined) construction, and a little more room through the chest and leg. The result is a jacket that drapes rather than grips – intentionally comfortable, never sloppy. It's the ideal answer to "anti-heat" dressing, where the goal is to stay cool while still looking tailored. For the same ease without committing to a full formal suit, a lightweight casual suit hits the mood perfectly.
The other notable shift is the return of the double-breasted jacket, now worn in a far easier way than its sharp-shouldered reputation suggests. A relaxed double-breasted blazer in linen or a lightweight blend gives real presence for weddings and evening events without feeling stuffy.
Statement trousers get roomier in spring/summer 2026 season
Trousers are following the jacket's lead. The skinny, ultra-tapered leg has had its day; in its place are straight, gently tapered and wider cuts, often with a forward pleat added back in for both comfort and a touch of vintage character.
For a smart-casual summer look, a pair of smart trousers or linen trousers in a neutral tone does most of the work. Dress them up with a blazer and loafers, or down with a knitted polo and boat shoes. If you'd rather keep things casual, well-cut chino trousers remain a reliable warm-weather staple, and when the heat really climbs, a pair of tailored shorts keeps daytime events smart without overheating.
Bold printed shirts
Summer is the one time of year to have a little fun with print, and spring/summer 2026 fashion leans into it. Botanical, abstract and nautical patterns are all having a moment, and prints are bigger and bolder than we've seen in recent seasons.
A standout printed or casual shirt is an easy way to inject personality – pair it with plain trousers so the shirt stays the focus. For the warmest days, a linen shirt or short-sleeve shirt keeps things breezy, whether you're at a barbecue, on holiday, or dressing down a blazer for a relaxed evening out.
Footwear: boat shoes, loafers and considered trainers
The footwear story this season is all about that effortless coastal feel.
- Boat shoes continue their comeback – the definitive Riviera-inspired shoe, perfect with cropped or rolled trousers and a crisp Oxford shirt.
- Leather loafers and slip-on shoes are the versatile workhorses, dressing up linen tailoring or finishing a smart-casual outfit with ease.
- Clean, considered trainers – ideally in leather or eco-minded materials – bridge the gap for casual days without letting the look slip.
For more formal summer occasions, a pair of polished brogues or Oxford shoes keeps a wedding or evening outfit sharp.
The return of the tie (and other finishing touches)
After several seasons of open collars, the necktie is making a comeback. It's an easy, low-cost way to lift an outfit and signal a bit of intent – a knitted or textured tie works especially well with summer tailoring, while a bow tie is the natural pick for black-tie summer evenings. A pocket square adds the final flourish for weddings and smarter events.
Beyond the tie, the knitted polo has become a season staple – smarter than a t-shirt, cooler than a shirt, and ideal under a blazer. Browse polo shirts and lightweight knitwear for that pulled-together, off-duty look.
Dressing for spring/summer 2026 weddings & formal occasions
Spring and summer are peak wedding season, and spring/summer 2026's relaxed tailoring suits the brief perfectly. For outdoor and destination ceremonies, lighter fabrics and softer construction keep you comfortable from the vows to the dance floor – a linen or lightweight wedding suit in an earthy neutral or soft pastel is a brilliant choice, while a sharp wedding blazer worked into mix-and-match separates offers flexibility as the day warms up. Three-piece looks are having a strong year too, with the contrasting waistcoat stepping up as the statement piece – try a navy suit with a soft ivory or camel waistcoat. And if the invitation says black tie, a summer-weight tuxedo is the way to go.
One trend worth leaning into: coordinated styling across the whole party. Matching or complementary outfits photograph beautifully, and they're an easy win for families. If you've got a little one in the wedding, our father and son suits and boys linen suits make it simple to pull a coordinated look together without it feeling forced.
Style that lasts: sustainability in spring/summer 2026
The good news is you don't have to choose between style and substance. The relaxed, natural-fibre, mix-and-match direction of spring/summer 2026 menswear is, by its nature, a more thoughtful one.
