the knee-length dress coat, morning coat and shorter cut lounge suit were all standardized. While the dress coat and the morning coat are knee-length coats like the frock coat and traditionally share the waist seam of the precursor, they are distinguished by the cutaway of the skirt which gives dress coats and morning coats tails at the back. From the 1920s, the frock coat was increasingly replaced as day formal wear by the cut-away morning coat. In 1936, it was suspended from the protocol of audiences at the British royal court. While effectively relegated to a rarity in formal wear ever since, it does occur in certain formal marriages and traditional processions. Name The name frock coat appeared out from the earlier frock. Earlier terminology also used redingote (or redingotte, redingot), derived from a French alteration of the English "riding coat", an example of reborrowing. History Frock coats emerged during the Napoleonic Wars, where they were worn by officers in the Austrian and various German armies during campaign. They efficiently kept the wearer warm as well as protecting his uniform. Privates and non-commissioned officers would wear greatcoats on campaign. The earlier frock During the mid seventeenth century the older doublets, ruffs, paned hose and jerkins were replaced by the precursor to the three piece suit comprising waistcoat, tight breeches and a long coat called a justacorps, topped by a powdered wig and tricorne hat. This coat, popularised by Louis XIII of France and Charles II of England, was knee length and looser fitting than the later frock coat, with turn-back cuffs and two rows of buttons. English and French noblemen often wore expensive brocade coats decorated with velvet, gold braid, embroidery and gold buttons to demonstrate their wealth. Before the frock coat existed, there was another garment called the frock in the 18th century, which was probably unrelated to the frock coat, sharing only a similarity in name. The earlier frock was originally country clothing that increasingly became common around 1730. Formal dress was then so elaborate that it was impractical for everyday wear, so the frock became fashionable as half dress, a less formal alternative. By the 1780s the frock was worn widely as town wear and, towards the end of the 18th century, started to be made with a single-breasted cut away front and tails. It was thus the precursor to the modern dress coat worn with white
