Based on a 1910s work shirt discovered in Ohio. The chinstrap, pockets for pens, wide front placket, and straight silhouette with no sloping shoulders have been inherited as much as possible from those days. The shirt has been made wider and shorter to make it more comfortable to wear. The fabric is again an original, special-order brand original, made of Supima organic cotton from the U.S. on an old-style power loom. 100% COTTON
