The 1840s and 1850s saw an increase in industrial production and mass-produced clothing in the United States and Europe. During the Gold Rush and Civil War, clothing was commonly purchased ready-made in local stores. This style of shirt was popular among gold miners and later worn by workmen and militia companies during the Civil War. Our reproduction is made of 100% wool flannel, machine-sewn with hand-finished buttonholes, and based on a pattern by Jim Miller, a historian of the Gold Rush. Our reproduction was patterned from images of original garments and features a wide placket, dropped sleeves, and two front patch pockets. The garment is intended to reflect the imperfections commonly seen in mass-produced clothing of the time, such as irregular buttonholes. It features a wide placket, dropped sleeves, and two front patch pockets. These are overshirts, not tailored to fit, so please order Small for sizes below 44, Medium for 44-46, Large for 46-48, and X-Large for 48+.
