Pinks and greens

"Pinks and greens" and "Army greens" are colloquial terms for the United States Army's officer winter service uniform of the early 20th century and the similarly patterned service uniform introduced in the early 21st century.
"Pinks and greens".
The "pinks and greens" uniform was introduced in the 1920s and consisted of a brownish green blouse (the "greens") with lighter colored trousers of a slight pinkish hue (the "pinks"). Accessories – which, until 1942, included a Sam Browne belt – were patterned in brown leather. In 1944, an optional field jacket, sometimes called the Ike jacket due its association with Dwight Eisenhower, was introduced. 
Beginning in 1948, wear of the uniform by officers was restricted to off-duty hours and informal evening social functions. The uniform was altogether deauthorized for officers of the United States Army effective February 1, 1958, and for officers of the United States Army Reserve and the Army National Guard of the United States effective October 1, 1959. 
The "pinks and greens" have been called "one of the flashiest and most striking uniforms ever authorized by the Army".
Army Green Service Uniform.
After a 60-year hiatus, on November 11, 2018, the U.S. Army announced it would adopt a new uniform patterned on the "pinks and greens" effective 2020, with phase-in to be complete by 2028. The decision to adopt the new uniform was done to fill the gap between the formal blue Army Service Uniform and the Army Combat Uniform created by the deauthorization of the old Army Green uniform used between 1954 and 2015. With the change, the blue Army Service Uniform will again be restricted to ceremonial wear. 
According to former Sergeant Major of the Army Daniel A. Dailey, the Army designation for the new uniform is "Army Green Service Uniform" rather than "pinks and greens".
