The “Mao suit” was designed by Sun Zhongshan in the early 20th century and was modeled on German military dress.

Following the establishment of the People's Republic of China in 1949, the suit became widely worn by government leaders as a symbol of proletarian unity and as the Eastern counterpart to the Western business suit. It was also introduced in other communist countries in Asia.

It has largely fallen out of use now.
