<P> A blood stripe is a scarlet stripe worn down the outside leg seams of trousers on the dress uniform of the United States Marine Corps . This red stripe is 2 inches ( 5.1 cm ) for general officers , 1.5 inches ( 3.8 cm ) for other officers , and 1.12 inches ( 2.8 cm ) for enlisted Staff Noncommissioned Officers and Noncommissioned Officers . Modified versions are worn on the officers ' evening dress uniforms , with the scarlet flanked with gold trim , and on members of the Marine Band , which wear the traditional red stripe with a white stripe in the center . </P>
