Women previously wore a uniform similar to the Service Dress Blue uniform but with a white coat and skirt or trousers. Officer's rank insignia consisted of lacing on the sleeves in the same manner as on the blue uniform, while CPOs wore rank insignia pins on the lapels of the jacket. However, the Navy announced female uniform changes to resemble the men's uniforms, and female officers and CPOs began wearing stand-collared tunics similar to the male uniform in early 2017, with full replacement of the old-style uniform by the end of January 2020 (delayed from an initial date of December 2019).
