A narrow-collar shirt jacket made from end-on-end chambray woven densely with Supima compact yarns. The design blends elements of 1920s French dress shirts, American workwear, and 1930s sack coats, all reinterpreted into a modern silhouette. The fabric is finished with a special bio-treatment, giving it a distinctive drape and smooth texture. Details such as the chest pocket and side slits contribute to a sharp, jacket-like appearance.
