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.
