The time-honoured trick to sprucing up your tailoring is to add a patterned shirt into the mix. Look to award-winning brand Richard James, who demonstrates a graphic dogtooth design in full effect on this pure cotton button-up. Cut to a streamlined fitted silhouette and tipped with a sharp spread collar, let the stand-out motif do all the work by adding a tonal tie and siding with a plain-weave suit.
