A longline trench cut deliberately loose, with a wide notch lapel that sits open across the shoulders rather than buttoning up tight. The self-tie belt does the shaping when you want it and hangs loose when you don't, which is really two coats in one silhouette.

Raglan sleeves and a yoked back keep the line soft instead of structured, so it drapes over whatever is underneath rather than fighting it. It is unlined and falls to mid-calf, which puts it in mid-season territory: enough coat to read as an outfit on its own, light enough to wear over a jumper without bulk at the shoulder. There is genuine room to layer, so the usual size is the right size even though the fit is generous.

It goes over joggers and trainers as readily as over tailoring, which is the whole point of a coat cut this way, and the belt is what lets it swing between the two. Black is the sharpest of the four and disappears under everything; beige and khaki sit warmer against denim and cream; army green is the one that reads as a choice rather than a default. Side pockets are deep enough to actually use, and the button front means it holds its shape closed on a colder day. The model is 5'6" and wears a size S.
