St James Jacket: Boiled Wool, Black. Precision-cut in a dinner jacket silhouette with a collarless neckline and tonal piping – and finished with heritage-inspired nickel crest buttons for a sense of occasion. In boiled lambswool, it’s impossibly comfortable, even when worn as part of a formal look. Pair with denim and a heeled boot. Or crank up the wool ratios by layering it over separates.
