These service stripes are of scarlet cloth on blue clothing and of blue cloth on white clothes. One service stripe is worn for each enlistment of three or four years that the wearer has completed. For petty officers who hold three consecutive good-conduct badges the service stripes are made of gold lace braid. _Neckerchief._—The neckerchief worn by enlisted men with the blue overshirt and white dress jumper is of black silk thirty-six inches square, worn around the neck under the collar, tied in a square knot just below the collar opening in front. _Leggings._—For duty with landing forces ashore enlisted men of the navy wear khaki-colored canvas leggings.
