Brown blazer by japanese brand LESVIS a BOIS (a sub-label of Abahouse, c. 1980s). Made from a brown speckled fabric composed of wool, silk, and nylon, it has a three button front, notch lapels, and two large patch pockets. The front of the jacket has a patchwork element, with a section of the jacket made in a contrasting beige fabric (particularly pleasing is the way the patch pocket, made in the main brown body fabric overlaps the edge of the patch).
