The slim denim shirt had its moment and that moment has passed for most of us. If you are not built like someone who counts macros for a living, a shirt that pulls across the shoulders and gaps at the chest is not doing you any favors. Regular fit is not a consolation prize. It is the cut that actually moves with you, layers properly over a tee, and tucks in without looking stuffed. The problem has always been that regular fit denim shirts can go soft and shapeless fast, losing any sense of intention by the third wear. What we have been looking for specifically are shirts that hold their structure through a proper collar, a clean placket, and fabric with enough weight to drape rather than sag. Worn open over a white tee with chinos or buttoned up under a wool overshirt, these are the ones that stay sharp without making you feel like you are being tested.
