Paul Smith Trousers & Joggers

PS by Paul Smith is the mainline diffusion range from the British designer Sir Paul Smith. It retains the same irreverent aesthetic as the main Paul Smith collection — signature stripe details, zebra logo patches and bold graphic prints — at a more accessible price point. The range covers everyday essentials including T-shirts, polo shirts, sweatshirts, knitwear and accessories.

Paul Smith is most closely associated with mixing British tailoring traditions with unexpected details: bold stripe linings, playful graphic prints and the now-iconic multicolour stripe motif. Founded in Nottingham in 1970, the brand became one of the few truly global British menswear names, known equally for its suits and its characterful casual pieces. The zebra logo is one of the most recognisable symbols in contemporary British fashion.

PS Paul Smith offers several fits across the range. T-shirts and casual shirts are typically labelled Casual Fit, which runs slightly relaxed through the chest and shoulders. Polo shirts are offered in Regular Fit, which sits true to size with a straight hem. Tailored pieces such as overshirts and chinos use a Tapered Fit for a cleaner silhouette. If you are between sizes, Paul Smith recommends sizing up.

PS by Paul Smith sits alongside — not below — the Paul Smith mainline. Both lines are designed in-house under Sir Paul Smith's creative direction and share the brand's core aesthetic. The PS range focuses on casual and smart-casual separates, while the mainline leans more heavily into tailoring and formal pieces. Quality, craftsmanship and design attention are consistent across both.

The PS Paul Smith clothing range is built primarily on high-quality cotton, ranging from organic cotton piqué on polo shirts to cotton-linen blends on overshirts and shirts. Sweatshirts use cotton-blend fleece, while knitwear introduces merino wool and cotton-blend jacquard constructions. The brand avoids synthetic blends on its premium pieces, keeping the focus on natural fibres that wear well and age gracefully.

The current range covers four styles across three distinct categories. The Tapered Fit Stretch Cotton Dark Navy Chinos and the Tapered Fit Blue Denim Jeans represent the smarter end of the range, both cut with a tapered leg that narrows from the hip to the ankle. The Hayden Black Jogging Bottoms and the Zebra Logo Patch Dark Navy Jogging Bottoms sit at the casual end, designed primarily for loungewear and relaxed everyday wear. All four styles are built in cotton or cotton-blend fabrics.

The PS Paul Smith chinos use a Tapered Fit — cut straight from the waist and hip before tapering gradually from the knee to a narrow ankle opening. The stretch cotton construction gives enough flexibility to sit comfortably without the stiffness of a pure woven fabric. They sit true to standard UK sizing at the waist; the tapered leg is designed to work with both trainers and clean leather footwear depending on the occasion.

Both jogging bottom styles are designed with enough finish quality to work beyond the home. The Zebra Logo Patch Dark Navy Jogging Bottoms in particular — with their branded patch and clean navy colourway — sit comfortably in the athleisure space when worn with a PS Paul Smith sweatshirt or hoodie from the same range. The Hayden Black Jogging Bottoms take a more minimal approach, making them the easier style to pair with a wider variety of casual tops.

The chinos use a stretch cotton twill construction that gives a cleaner, more formal line than denim — they read as smart-casual and pair naturally with shirts, polo shirts and knitwear. The Tapered Fit Blue Denim Jeans use a medium-weight cotton denim in a mid-blue wash, offering a more casual silhouette that works well with T-shirts and sweatshirts. Both share the same tapered leg cut, so the silhouette is consistent — the difference is primarily in occasion and styling versatility.

Stretch cotton chinos should be machine washed at 30°C on a gentle programme to preserve both the stretch fibres and the colour depth of the navy fabric. Turn dark navy and black pieces inside out before washing to slow colour fading. Denim jeans can be washed less frequently — every four to six wears — to maintain the indigo wash and fabric structure. Jogging bottoms can be washed at 30°C on a standard cotton programme; reshape while damp and hang or lay flat to dry.

The Tapered Fit Stretch Cotton Dark Navy Chinos are the most appropriate style for smart-casual occasions — pairing well with a PS Paul Smith tailored shirt, polo or fine-knit cardigan for work environments, dinners or events where jeans would be too casual. The denim jeans in a clean mid-blue wash can also work in relaxed smart-casual settings when worn with a structured shirt or overshirt. Jogging bottoms are better reserved for casual and leisure contexts.
