A car coat sits somewhere between a jacket and a full length topcoat, usually landing at the hip or upper thigh. It was originally cut short so drivers could sit comfortably, and that practical length is exactly why it works so well now. It covers a chunky sweater without swallowing your shape, it does not drag when you sit on the train, and it looks right over straight jeans, wide trousers and midi skirts alike. Look for a clean collar, a single row of buttons and a fabric with some weight, like boiled wool, melton or a soft wool blend. Camel and charcoal are the easiest colors to wear daily, while cream and plaid feel a little more special. Because the shape is so simple, small details matter, so pay attention to pocket placement, shoulder fit and how the hem falls when it is buttoned.

The car coat is at its best with a straight or slightly relaxed leg, so the hem lines up neatly with the top of your trousers. A turtleneck or crewneck sweater underneath keeps the neckline clean. For a dress, choose a midi length so the coat reads as intentional rather than too short. Loafers, ankle boots and simple sneakers all work, which makes it one of the most versatile layers you can buy for colder months.
