Suits & jackets Size Guide

The pieces of a Belvest tailored waistcoat are laid out on a table, being measured by a tailor.

To help you to select the right size for garments, we have created size guides shown below. For your convenience the Robert Old customer experience team has individually measured all garments.

To find your ideal clothing size we would recommend comparing our measurements to similar garments that you already own, ensuring that they are laid flat before measuring.

If you would like any additional advice please feel free to contact us via +44 (0) 1202 290832 or store@old.co.uk and one of our friendly team will get back to you as soon as possible.
