round-toed boots (referred to as boondockers), preferably with steel toes. The blue utility jacket was authorized in climates not cold enough as to warrant wearing the black All-Weather Coat. Enlisted Undress Blues Prior to the introduction of the Winter Blue/Winter Working Blue uniform, personnel E-6 and below in office and classroom environments were authorized to wear the Undress Blue uniform; this broadly resembled the Dress Blue "crackerjack" uniform but carried no piping or stars, and the sleeves were wide and cuffless. Before 1941 this was the standard working uniform for all "above-deck" duties since dungarees were not permitted anywhere the public might see them. Ribbons and neckerchief were not worn and the uniform was not authorized for liberty. Enlisted Dress Whites (prewar) Until 1941, the summer and tropical equivalent to the Dress Blue "crackerjacks" was a white cotton jumper uniform with blue collar and cuffs. The elongated, "tar-flap" collar was adorned with white piping and stars like the blue uniform. This uniform was discontinued "for the duration" and was never reinstated; instead the Undress Whites with the addition of ribbons and neckerchief became the summer dress uniform for sailors. The "Flat Hat" From 1852 until 1962 (although in practice rarely worn after the middle of World War II), enlisted sailors were issued a round, flat blue wool sailor hat with a ribbon around the band similar to that worn by the Royal Navy. The "Donald Duck" was worn with the Service Dress Blue uniform on more formal occasions in lieu of the white "Dixie cup." The ribbon carried the name of the wearer's ship or station embroidered in gold until 1941, when this was replaced with a generic "U.S. Navy" as a wartime security measure. The "Bucket" Cover for Female Officers and chief petty officers From 1940 until 2018, U.S. Navy female officers and chief petty officers were issued "Bucket" Cover.
