Black, Navy, Blue & Grey Double Breasted Blazers
Colour is one of the easiest ways to decide how formal or versatile a double breasted blazer will be. A black double breasted blazer creates a sharp evening look and works particularly well with monochrome outfits, formal trousers and polished shoes.
Navy and blue double breasted blazers are versatile choices for weddings, dinners, work events and smart occasions. Pair them with grey, beige or navy trousers depending on how formal you want the outfit to feel.
Grey and charcoal jackets provide a classic alternative to navy and black, while beige, green and other seasonal colours can create a more distinctive look for spring, summer and occasion dressing.
Slim Fit & Tailored Double Breasted Jackets
The fit of a double breasted jacket is particularly important because the overlapping front naturally creates a more structured silhouette. A slim fit double breasted blazer gives a closer outline through the body, while a tailored fit offers a shaped appearance with a little more room.
The shoulders should sit cleanly, the front should fasten without pulling across the chest and the jacket should keep its shape when buttoned. Check the individual product measurements and compare them with a blazer or suit jacket you already own if you are unsure which size to choose.
Double Breasted Blazer or Double Breasted Suit?
A double breasted blazer is designed to work as a separate jacket, giving you more freedom to combine it with contrasting trousers, shirts and accessories. This makes it useful when you want a polished outfit without wearing a complete matching suit.
If you want the jacket and trousers to match as a complete formal outfit, browse our men's double breasted suits instead. Keeping the blazer and suit collections separate makes it easier to choose between coordinated tailoring and a mix-and-match look.
Check, Tweed & Statement Double Breasted Blazers
Check and tweed double breasted blazers add more texture and character than a plain jacket. They work particularly well for autumn and winter events, race days, country-inspired outfits and occasions where you want the jacket to become the main feature of the look.
Keep the rest of the outfit relatively simple when wearing a patterned blazer. Plain trousers and a crisp shirt allow the check or tweed pattern to stand out without making the overall outfit feel too busy.
How to Style a Men's Double Breasted Blazer
For a clean formal outfit, wear a double breasted blazer with a crisp men's formal shirt, smart trousers and polished brogues or Oxford shoes.
Navy, black and grey jackets work particularly well with simple shirts and understated trousers. If the blazer has a bold check, tweed texture or stronger colour, keep the shirt and trousers more neutral so the jacket remains the focus.
For smart-casual dressing, wear the blazer with tailored trousers or chinos and an open-collar shirt. A double breasted blazer can be worn open for a more relaxed look, although fastening it usually creates the sharper structured silhouette associated with the style.
Double Breasted Blazers for Weddings & Formal Events
A double breasted blazer can be a strong option for wedding guests, groomsmen, dinners, race days and other formal celebrations. Navy, black and neutral styles create a classic look, while check, tweed and coloured jackets offer something more distinctive.
If you are specifically shopping for wedding tailoring, browse our men's wedding blazers. For black tie or more formal evening dress codes, our men's dinner jackets may be a better fit.
Complete the Look
A double breasted blazer already creates a strong visual shape, so keep the rest of the outfit balanced. Pair patterned jackets with plain trousers and simple shirts, or style navy, black and grey jackets with a tie and pocket square for a sharper finish.
Complete the outfit with men's formal shirts, smart trousers and men's brogues and Oxford shoes.
