We use different suppliers for our products and we are in the process of creating a unique size chart for each supplier. You can take a look at the size chart for each supplier by simply clicking on the brand icon below. We are also in the process of adding a tape measure symbol to each product details page which will take you straight to the appropriate size chart for each product. Please note that sizing will always vary even within a brand depending on the cut and style of the garment e.g. loose fitting, fitted etc. If you would like any specific advice please do not hesitate to call us on +44 (0)1668 283300. We are always happy to whip out a tape measure and check the size of a garment for you!
