optionally on the shirt. Command nametags were also optional on both the blouse and/or shirt. Brown shoes were typically worn, although this transitioned to black between 1975 and 1986 when brown shoes were discontinued. Following the reinstatement of brown shoes in 1986, brown shoes again became the most common footwear. Authorized headgear included a combination cover in green, or a green garrison cover. During World War II and the Korean War, ribbons were also authorized with this uniform, making it a de facto "service uniform" or "liberty uniform," authorized for wear off base. But by the early 1960s, it had become limited to that of a "working uniform" for use on base or aboard ship only. It was infrequently worn, primarily due its expense and its 100% wool fabric that typically made it unsuitable outside of the winter months; in the working environments where AWGs were authorized, aviators typically found working khakis or flight suits more convenient. The AWG uniform was formally phased out on 1 January 2011 along with several other uniforms as part of an extensive U.S. Navy uniform consolidation. The Type I Navy Working Uniform took its place. Tropical Uniforms The rarely seen Tropical White Uniform (also referred to as Tropical White Short) was similar to the Summer White Service uniform, except white knee shorts and knee socks were worn. It was colloquially known as the "Captain Steubing" uniform, after the character on The Love Boat TV show. Exceptionally rarely worn, though authorized with this uniform, was a pith helmet, with a Naval Officer's insignia at the front, above the brim. Tropical working uniforms existed, but were variations on the working khaki and utility uniforms. Knee shorts and black knee socks are worn, along with short sleeved button-up shirts. Summer White/Blue ("Salt and Pepper") Initially worn by E-6 and below beginning in the mid-1970s with the temporary phaseout (until 1982) of the traditional "crackerjack" uniforms, it was later expanded to include chief petty officers and commissioned officers. Best known by the nickname "salt and peppers," the uniform consisted of a summer white shirt and winter blue (e.g. black) trousers for males and summer white blouse and winter blue trousers or winter blue skirt for females. The uniform was worn with a combination cover and black shoes. Although naval personnel still retained all the components that made up this uniform, its use was discontinued in 1983. Though the
