cold weather, a jumper was knitted from yarn or wool. For wet weather, old sail cloth was made into a coat (with hat or attached hood) that was waterproofed with tallow or fat. In these days, the officers would designate certain afternoons to "make and mend" (clothing). A sailor with little clothing to make or mend used this time as "time off". In January 1857 the decision was taken to issue complete uniforms to petty officers and seamen. This included features which can still be recognised in the Class I uniform of ratings in the modern Royal Navy - notably the wide blue collar with white tapes, a black neckerchief, white lanyard and blue or white jumper. The flared "bell bottom" trousers disappeared after the Second World War. Because of the global dominance of the Royal Navy from Trafalgar to the Second World War RN uniforms became the model for virtually all other navies. While certain distinctive features emerged - such as the red pompon worn on the crown of the French sailor's cap, the open fronted jacket of the German Navy or the white round cap of the U.S. Navy - the overall pattern remained standard until the development of specialist working or protective rigs during the Second World War. American Civil War It is generally supposed that Union soldiers wore blue uniforms and Confederate soldiers wore grey ones. However, this was only a generalisation. Both the Union and the Confederacy drew up uniform regulations, but as a matter of practical reality neither side was able to fully equip its men at the outbreak of the war. Existing state units and quickly raised volunteer regiments on both sides wore a wide variety of styles and colours in the early stages of the war. Some regiments—such as the North's Berdan Sharpshooters and the South's Alexandria Rifles—had green uniforms, while the French zouave style was widely imitated. The Union eventually got most of its men into regulation Federal blue but this often faded until it appeared grey. Originally the Confederate government relied on the "commutation" system which required the states to provide their own uniforms. While the commutation system was in place, many states were not able to provide an ample supply of uniforms and captured federal uniforms were common. Later in the war the Confederate national government provided uniforms from a central depot system, including the famous Richmond and Columbus
