A casual suit takes the principles of traditional tailoring and gives them greater freedom. Peter Jackson’s collection of men’s casual suits brings together coordinating sport jackets and tailored trousers in premium fabrics, considered textures and versatile seasonal tones—creating complete looks that feel polished without appearing overly formal.
Wear the jacket and trousers together for an easy alternative to conventional suiting, or separate them across the rest of your wardrobe. The collection spans wool-linen blends, cotton-linen cloth, premium babycord and other textured constructions that bring greater depth and ease to modern tailoring.
The result is suiting designed for occasions where a traditional business suit might feel too rigid: casual weddings, dinners, creative workplaces, long lunches and events where the dress code leaves room for personality.
What Is a Casual Suit?
A men’s casual suit is a coordinated jacket-and-trouser combination designed to feel less formal than traditional business or evening tailoring. The distinction comes through fabric, texture, colour and styling rather than abandoning the structure of a suit altogether.
Wool-linen blends introduce natural texture and lighter character. Cotton-linen styles lean further into relaxed warm-weather dressing, while babycord adds depth and a more tactile finish.
This flexibility is central to casual suiting: wear the pieces together as a complete outfit, then break them apart when the setting changes. For an even broader approach to interchangeable tailoring, explore our Suit Separates.
Casual Suits in Wool, Linen, Cotton & Textured Fabrics
Fabric does much of the work in contemporary casual tailoring.
A wool-linen suit retains the natural drape and refinement associated with wool while introducing the texture and relaxed character of linen. Cotton-linen styles offer an easier warm-weather expression, while premium babycord gives tailoring a richer surface suited to transitional dressing.
Rather than relying on overt detailing, these fabrics allow weave, texture and finish to provide character. Grounded shades, seasonal tones and subtle pattern make the pieces easy to integrate with the rest of a modern wardrobe.
For another interpretation of coordinated dressing, our Co-ords Edit brings together matching pieces designed to work as a complete set or independently.
How to Wear a Suit Casually
The easiest way to make a suit feel more relaxed is to change what surrounds it.
Swap the traditional business shirt and tie for an open-collar casual shirt, a breathable linen shirt, knitted polo or fine-gauge knitwear. The tailoring remains considered, but the overall outfit becomes softer and less prescribed.
Footwear can shift the tone just as effectively. Suede or leather loafers work naturally with textured tailoring, while clean sneakers push the look further off-duty. When the setting calls for another degree of polish, classic Derby shoes provide a refined middle ground.
Tonal dressing is another natural fit for casual suiting. Keep the jacket, trousers and top within related shades, then use differences in fabric and texture to create depth without relying on hard contrast.
Can You Wear a Casual Suit to a Wedding?
Yes—a casual suit can be an excellent wedding option when the dress code, venue and time of day allow for a less formal approach.
Textured wool, linen blends, babycord and softer seasonal colours feel particularly natural at garden, winery, beach and contemporary weddings. They maintain the consideration expected of wedding attire without carrying the rigidity of traditional business tailoring.
Pair a coordinated casual suit with a crisp shirt and loafers for relaxed polish, or introduce a silk tie and pocket square when the occasion calls for greater formality.
For ceremonies with a deliberately relaxed dress code, explore our Casual Weddings collection. For something more directional, built around distinctive tailoring, richer fabrics and stronger silhouettes, see Contemporary Weddings.
Wear the Jacket and Trousers Together—or Separately
One of the strongest reasons to invest in casual suiting is what happens after the complete outfit.
A textured sport jacket can return with chinos, denim or contrasting tailored trousers. The matching trousers can move into another look with knitwear, a casual shirt or lightweight outerwear. Breaking the suit apart extends the role of both garments and creates more combinations without requiring an entirely new outfit.
For more traditional tailoring, explore Peter Jackson’s wider men’s suits collection. Casual suits occupy a different space: they retain the cohesion and proportion of a suit while allowing each piece greater independence.
