Wearing The DB As A Separate
One of the simplest ways to make a double‑breasted jacket feel less formal is to stop thinking of it as part of a suit and start treating it as a separate. Breaking the jacket away from matching trousers immediately relaxes the look and opens up a host of styling options.
Colour does a lot of the work here. A navy or stone DB in a textured cotton‑linen blend becomes incredibly versatile when worn with something like off‑white chinos or even light‑wash denim. By keeping the rest of the outfit grounded in casual pieces, the jacket feels like a natural step up from a chore coat or overshirt, rather than a formality to be “dressed down”. Texture is just as important. Fabrics with slub, open weaves or a dry hand finish naturally soften the profile of a double‑breasted jacket and prevent it from feeling too slick. This season’s Oliver Spencer DBs lean into those tactile cloths, making them easy to pair with everything from knitted polos to crisp tees.

Casual Summer Pairings
To make the most of a double‑breasted jacket in a relaxed summer wardrobe, start with combinations that feel intuitive and comfortable, then let the silhouette do the elevating. A soft navy DB worn open over our Heavyweight white tee and straight‑leg Morton trousers or our wide-leg Orsman trousers is an effortless way to sharpen up a weekend uniform without sacrificing comfort. Neutral lo-fit trainers or suede loafers keep the whole look grounded and modern.
For high‑summer days, try a lightweight double‑breasted jacket over a fine‑gauge knitted polo and tailored shorts in a complementary tone. The jacket adds structure to a casual foundation, while the open collar and bare ankle keep the mood firmly off‑duty. A textured DB over a patterned camp‑collar shirt and clean, straight‑cut jeans is a useful smart‑casual formula for smart-casual dinners, gallery visits or evenings on holiday. Each of these looks works particularly well with the kind of relaxed unstructured tailoring that Oliver Spencer is known for: jackets that sit lightly on the shoulders, move with you during the day, and never feel over‑engineered.

Styling Details That Make The Difference
Once you have the broad outfit combinations in place, small styling decisions go a long way to keeping a double‑breasted jacket feeling relaxed. Wearing the jacket open softens the line and lets the fabric move more freely, eschewing that wrapped look when fastened. When you do fasten it, try buttoning just the main anchor button rather than cinching everything tight; this maintains the shape without feeling rigid. Rolling or gently pushing up the sleeves slightly can also help signal that the jacket is there to be lived in, rather than preserved.
Footwear is another key lever. Switching from formal oxfords to something like leather or suede loafers, clean sneakers, or minimal sandals changes the whole energy of the look, especially in summer. The same goes for shirting: choosing open collars, camp collars, knitted polos or a simple crew neck over a shirt‑and‑tie combination will keep the DB in relaxed territory without losing its inherent elegance.
Making The DB Part Of Your Everyday Wardrobe
Ultimately, the modern double‑breasted jacket is less about following rules and more about embracing a shape that offers a bit more presence than a single‑breasted blazer. With softer construction, breathable fabrics and a focus on relaxed unstructured tailoring, our current DB styles are designed to slip into your existing wardrobe without any fuss. Worn as a separate over casual foundations, it becomes a summer workhorse: a piece you can throw on for dinners, weekends away, or city days when you want to look considered but not over‑dressed. Once you start thinking of it as an easy, everyday layer rather than something reserved for “special occasions”, it quickly becomes one of the most versatile jackets you own.
