The following is a rough guide for international size conversions. We emphasize that this is only a guide, as sizes vary from brand to brand and country to country. Please note that sizings are individually named within the Smooth range, as we are labelling according to how we see the optimal fit of a garment- this will vary from style to style. Your correct size may be different in two different garments. Therefore, please measure yourself before ordering, and bear in mind that knit garments are usually better a little loose rather than a little tight.
