This traditional sleeveless garment is called a Bei Xin 背心 (Bèixīn). This style of Bei Xin was worn by men engaged in physical labor to maximize arm mobility while preserving modesty and staying warm. Fans of Hong Kong cinema will recognize it from martial arts films. These indigo-blue hemp Bei Xin are in the distinctive Tangzhuang style. Dating back to the Qing dynasty, the Tangzhuang is a fusion of Han and Chinese sartorial traditions. It is characterized by its distinctive cloth buttons and Mandarin collar.
