Work jacket, made in London, with heavy corduroy from Lancashire, and horn buttons — removable ones — from the West Midlands. The work jacket fits true to size — but note that it is one of the more short jacket styles in these parts. This is cotton, yes — but with elements which are not cotton. The sleeve-lining, for instance, and the buttons, of course. As such, it is best washed by hand in lukewarm water, or dry cleaned. If a machine must be used, a cold wash and no tumble-drying is the only option.
