According to The Greenwood Encyclopedia of Clothing through World History the Chesterfield style of overcoat was invented by the 6th Earl of Chesterfield in the 1840s. It was designed without a tight waistline seam to have a looser, more comfortable fit, a big change from the rigid and structured top coats that preceded it. It can be either single or double breasted, although single is the traditional style. It often has conceled buttons, a.k.a. a ‘fly front’, and is distinguished by a velvet collar in a complimentary color. Various tweed and houndstooth patterns are common for Chesterfield coats, as is the traditional wool or cashmere. I’ve always thought the detailed patterns, highlighted by the colored velvet collar, made this a singularly stylish piece. While they are still around today, they are not as popular as a regular wool, solid color top coat and therefore are harder to find and generally quite expensive. The first example below is a very traditional navy blue wool coat from Brooks Brothers, the second is a much more high fashion example from Burberry, and finally a fast fashion version from Topman. All have the essential look that distinguishes the Chesterfield, and it’s owner, as gentlemanly. So if you see one try it out, it may add something very unique and new to your cold weather wardrobe.
