These were ordered as slim fit. Now I have had slim fit previously but in different material. This style of slim fit had too narrow a lower leg compared to other slim fits. I think it could be useful if the actual width of the bottom of the leg could be indicated in advertising or that there was a standardisation of the leg width irrespective of style.
Response from Charles Tyrwhitt:
It's disappointing to hear these chinos didn't fit as expected due to how slim the legs were. I have reviewed our sizing guides and the size of the leg opening is provided but we will take your feedback on board about providing more information. I can see these have been returned and your refund has been completed.
