In the second half of the 18th century, the justacorps skirt decreased in fullness, becoming narrower. A straight edge, similar to 17th-century-style openings, replaced the rounded opening of the coat, and sleeves reverted to a deep, turned back cuff. Textiles for the justacorps varied by use. Durable fabrics, like wool, were used in ordinary, everyday situations, and typically had less ornamentation compared to ones worn in elegant, formal settings. These coats were made of ornate fabrics like silk and brocade, and decorated with elaborate embroidery and lace.
