Blazers
Men's Blazers
Men's blazers from Hackett London sit at the centre of British tailoring: structured enough for a board meeting, relaxed enough for a long lunch in Chelsea, and built in cloths chosen for how they wear, not just how they look.
Cut, construction and the shape of the shoulder
The canvas decides how a blazer moves. The finest of our men's blazers use a floating canvas, a layer of horsehair and wool left free between cloth and lining rather than glued in place, so the chest follows the body and the lapel rolls naturally instead of lying flat. The single-breasted two-button shape covers most occasions. Double-breasted blazers add a broader, more assured line, formal blazers sharpen it for evening and ceremony, and casual blazers soften it with a lighter, unstructured shoulder.
Cloth through the seasons
Cloth sets the season. Flannel blazers carry a soft, brushed hand through autumn and winter, while tweed blazers bring weight and texture for the country and the coldest weeks. Linen blazers breathe through July and August, creasing the way linen should. A year-round worsted sits around 260 g/m²; winter cloths go well above 350. Across all men's blazers, pattern adds another layer: checked blazers, from fine glen check to bold windowpane, turn plain trousers into an outfit, and a half-lined back keeps the lighter cloths cool.
Navy and beyond: choosing a colour
Navy remains the most useful colour in tailoring, which is why blue blazers anchor the collection. Grey blazers sit just behind, quiet over white shirts and dark denim. Black blazers belong to the evening, brown blazers to the weekend and the country, green blazers to men who like a little character, and white blazers to summer parties and the riverbank. Our men's blazers in each shade share the same construction; only the mood changes.
How to wear men's blazers
The best men's blazers earn heavy rotation because they work with trousers you already own. Keep the sleeve short enough to show a centimetre of shirt cuff and the length long enough to cover the seat. A natural shoulder keeps the line soft over knitwear. Two ways to wear one:
Navy blazer over a white Oxford shirt, stone chinos and brown suede loafers: Saturday lunch on the King's Road, followed by a slow walk home.
Grey flannel blazer over a pale blue shirt and knitted silk tie, charcoal trousers and dark brown brogues: a Thursday on Jermyn Street that ends with dinner in St James's.
Since Hackett London opened its first shop on King's Road in 1983, the blazer has been the garment the house returns to most. Look at the lapel buttonhole. On a well-made blazer it is cut and finished by hand, with a tight, even stitch that will outlast the cloth around it.
What is the difference between a blazer and a suit jacket?
A blazer is designed to be worn as a stand-alone jacket with contrasting trousers, while a suit jacket is cut from the same cloth as its trousers. Blazers often use more textured cloths, patch pockets or contrast buttons. A suit jacket worn alone tends to look like half a suit.
How should men's blazers fit?
Men's blazers should sit flat across the shoulders, with the seam ending at your natural shoulder bone. The front should close without pulling, and the sleeve should show about 1 cm of shirt cuff. The length should cover the seat of your trousers.
What colour blazer is the most versatile?
Navy is the most versatile blazer colour, working with grey, stone, white and denim trousers. Mid-grey comes a close second. Start with navy, then add grey or a textured cloth such as flannel or tweed.
