Broadly speaking, ‘casual tailoring’ means making your suited look a little more undone. Think unstructured jackets paired with tailored trousers, or style your suit with a grandad shirt and swap buttonholes for badges, as seen on the catwalk at Dior Homme. The element of slouch is all-important – see Sam’s loose-fitting linen-mix T-shirt and the wide-leg trousers worn by Ty for just the right smart/casual balance. Finish the look with white pumps for come-as-you-are nonchalance. Helen Seamons
