Update October 2026. This article dates from summer 2026. For the current season: Men's winter 2026 coats: the cuts to adopt · This season's menswear.
With summer 2026 just around the corner, the question of the men's summer 2026 look is back in the spotlight. How do you dress for long days, sunny terraces, and air-conditioned offices with the same casual elegance? At Appart17, we have selected five outfits that solve this equation: mastered casual chic, designed for today's Brussels lifestyle. From Monday morning to Friday night, here is our lookbook for the season.
Look 1 — The office without a tie: linen shirt + tailored chinos
For a day at the office when temperatures rise, it all comes down to light fabrics and structured cuts. We recommend an open-collar linen shirt from Selected Homme, worn tucked into straight-fit chinos in sand or light khaki tones. A soft leather loafer finishes the ensemble with sharpness. The trick that makes the difference: roll up the sleeves slightly to expose the wrist and lighten the silhouette. This look holds up from the 9 a.m. meeting to the late-afternoon drink, without the slightest apparent effort. Find Selected Homme pieces in our dedicated selection.
Look 2 — The weekend terrace: textured polo + slim jeans
The weekend deserves a more relaxed, but no less polished, tone. A fine textured knit polo in breathable cotton, worn with lightly faded slim jeans: this is the winning combination for a city terrace or brunch with friends. At Les Deux, pieces blend Scandinavian manufacturing quality with colors that are easy to match—lavender blue, ecru, soft terracotta. Complete the look with low-top canvas sneakers or light derbies. Simple, yet composed. Our Les Deux selection offers exactly this type of balance between overt relaxation and assertive style.
Look 3 — Everyday casual: premium t-shirt + wide-leg trousers
The most worn look of the summer remains the one you throw on without thinking—provided you have the right foundations. A heavyweight cotton crew-neck t-shirt, neither too tight nor too oversized, paired with wide-cut trousers in a light fabric: this is an outfit that gains character through the quality of its pieces rather than their complexity. Solid shades—optic white, black, heather grey—allow you to mix everything without calculation. If you are looking to refresh your essentials, our men's ready-to-wear department brings together wardrobe staples chosen to last for several seasons.
Look 4 — The summer evening: light jacket + monochrome outfit
When the evening sets in and the light in Brussels turns golden, the monochrome effect is a formidable stylistic weapon. Combining trousers and a t-shirt in similar tones—beige and sand, navy and slate, khaki and olive—creates an elongated and coherent silhouette. Layer on a lightweight unstructured jacket, such as a coach jacket or soft cotton blazer, to mark the transition between day and night. Selected Homme offers jackets of this type with a cut that dresses you up without suffocating—a real asset for evenings where the temperature remains mild until the very end.
Look 5 — The urban getaway: chic bermuda shorts + open shirt
Bermuda shorts have definitely moved on from the beach and into the city. Provided you choose them in a slim fit, a fine material—twill cotton, light linen—and a length that falls just above the knee. At Appart17, we favor bermuda shorts whose finish rivals that of chinos. Wear them with a light short-sleeved shirt, left open over a basic t-shirt, and leather sandals or mules. To explore our bottom options, head to our men's trousers and jeans section, which also features the season's bermuda cuts.
The rules of men's casual chic style in summer
Beyond the five looks, a few principles guide our choices for men's fashion in Brussels for summer 2026. First, materials: linen, light cotton, fine jersey—avoid anything that retains heat unnecessarily. Next, the palette: neutral colors and earthy tones facilitate combinations and span the seasons. Finally, the fit: a well-tailored piece always compensates for the simplicity of an outfit. Men's casual chic style is not a question of budget or visible logos, but of coherence between pieces and attention to detail—a collar that holds its shape, a clean hem, a color that works well with others.
These five outfits cover the essential summer occasions without ever sacrificing comfort for elegance—or vice versa. Find our complete selection at appart17.be or come and discover our pieces in our three shops at Rue des Grands Carmes 11, 15 and 17 in Brussels.
