Arming doublets were worn under plate armor from the 15th century onward. The laces on the doublet allowed soldiers to attach armor pieces directly to the garment. The arming doublet evolved from the gambeson and the 14th-century pourpoint. Padding on the inside protects the body against blows transmitted through armor pieces. In the late Gothic style (1450–1500), arming doublets were often fitted with voiders and a chainmail skirt (gousset). In late 15th-century Italy, this also became a civilian fashion: men who were not knights wore arming doublets, probably because the garment suggested status and chivalry.
Pair the doublet with trousers or chausses, laced directly to the garment. Typical features include a close-fitting cut, a small standing collar, and a closed or buttoned front. Originally worn as a high-necked under-jacket, the doublet's neckline grew lower during the Renaissance and its decoration became richer. A light shirt or undershirt was typically worn underneath.
Images of doublets from the late Middle Ages and the Renaissance appear in abundance — for example in the Codices Palatini germanici 466.
Made from cotton with a close-fitting cut, this doublet features contrasting details throughout. A burgundy lace closes the center front. Additional laces run along the sleeve hems and the bottom edge. Use the bottom laces to attach hose directly to the doublet. The lining is a light, contrasting cotton fabric. This is not an armored doublet.
Wear this doublet under armor in a historically accurate manner. Laces are included for attaching armor pieces.
