These are the same as the white uniforms currently worn by commissioned officers. Like with commissioned officers, a white tunic may be worn with 1AW dress and 1BW dress when "required to conform with accepted international standards of dress on state or major ceremonial occasions, but the white tunic worn by senior rates differs from that of commissioned officers in that it only has four buttons rather than five and does not feature shoulder boards nor fittings for them. Petty officers wear blue on white versions of their substantive rate, trade, and good conduct badges with the tunic, Chief Petty Officers wear their cuff buttons and a gold on blue trade badge above the right cuff, and Warrant officers wear gold on white versions of their sleeve rank badges.
