The Chesterfield coat is a long, tailored overcoat. It arose along with the lounge suit as an alternative to the highly shaped coats it replaced, such as the frock overcoat with its heavy waist suppression using a waist seam. The Chesterfield has no horizontal seam or sidebodies, but can still be somewhat shaped using the side seams and darts. It can be single- or double-breasted, and has been popular in a wide variety of fabrics, typically heavier weight tweeds, or charcoal and navy, and even the camel hair classic. It has often been made with a velvet collar. These variations make it extremely versatile, so it can be worn with a city suit or even semi-formal dress, as well as casual sports jackets. It was a staple of smartly dressed men's wardrobes from the 1920s to 1960s, and is still very commonly worn.
