nounThe Mao suit is the western name for the style of male attire known in China as the Sun Zhongshan suit or Zhongshan suit (中山装, Zhong1shan1 zhuang1, or 中山服, Zhong1shan1 fu2), named after Sun Zhongshan (Sun Yat-sen) who introduced it shortly after the founding of the Republic of China. In accordance with the Chinese tradition of changing the style of dress for different dynasties, Sun Yat-sen instructed that a new form of clothing be designed for the new republic.
