Sienna Twill Black Trousers
Crafted from a luxurious wool and linen blend woven at the renowned Italian mill Tessuti di Sondrio, the Sienna Black Trousers strike a refined balance of lightweight breathability and natural structure. The fabric’s clean drape and soft hand feel ensure comfort and elegance, while classic tailoring details—including pleats, side waist adjusters, and cuffed hems—add timeless sophistication to this versatile design.
The Sienna Trousers are an essential building block of modern tailoring. Pair them with the coordinating Luzio Jacket for a complete look, or dress them down with a fine-gauge knit or casual blazer for off-duty refinement. Their neutral black tone makes them endlessly versatile, complementing crisp whites, tonal greys, earthy shades, or bold contrasting colours season after season.
Sizing Information
Designed with a relaxed fit and light taper, the Sienna Trousers drape naturally from waist to ankle, enhanced by pleats and cuffed hems for a refined finish. Model is 185cm tall, wearing an 84 trouser.

What's My Size?
Find the perfect fit with our size chart. We offer 3 different fits for our tailored suits: Regular, short and long. These are determined by the length of the sleeve and jacket with a 3cm difference between fittings.
Our trouser sizes go up in increments of 4cm. If your waist (point A.) measures 88cm, your trouser size is 88. If your waist is 90cm, it's better to go up to size 92 - always best to leave room for comfort.
Find the ultimate tailored companion with the right fit. Our tailored business shirts feature the signature cutaway collar. For a custom longer sleeve shirt contact us through our Made to Measure programme.
Our exclusive range of premium leather footwear is designed with UK sizing in mind. See the table to the right for reference. If you're not sure about your size feel free to contact us via our contact form.
A. Chest: With a tape measure wrap around the chest, pulling the tape firmly to gauge your centimetre measurement.
B. Sleeve Length: With the arm naturally down, measure from the tip of your shoulder - where the shoulder seam meets the sleeve head down to the wrist. Please note - if you are purchasing a 2 piece suit, the trouser size that will come with the jacket is preselected.
