From the very beginning, getting the right size has been an important part of the Charles Tyrwhitt DNA. We offer a greater range of sizes than all of our competition because we recognise how important it is to make a garment feel great to wear. In addition to our three core fits; Classic (“fuller”), Slim (“regular”), and Extra Slim (“Tailored”), we offer a vast combination of collar and sleeve options, so it is a shame that you've not yet found the perfect combination. We keep the sizing of our items consistent so you can be confident when re-purchasing. Dimensions will only ever change after much debate and customer feedback and when we are sure that a small tweak will improve the overall fit. Our sizing guides, which can be found on every product page will help you choose what is best for you and give clear instructions on how to measure yourself. If you need further help, we are available on webchat or by phone.
