Fit is all about the shape of the jacket: slim, regular or relaxed. The fit you prefer will depend on the style and look you prefer.
Slim Fit: Form fitting, tailored at the shoulders, body and waist. These pieces offer a more active fit that sits close to the body.
Regular Fit: Standard fitting, tailored at just below the waist. These pieces often offer a flattering fit without being too tight or constricting, and are true to size.
Relaxed Fit: A larger fit, little to no tailoring with more room in the shoulders and chest. These pieces offer more room for comfort and layering.
