Banbi

Banbi (Chinese: 半臂; lit. 'half-arm'), also known as banxiu (半袖; 'half-sleeves'), is an upper garment item in Hanfu. It was sometimes referred to as beizi (褙子) or half-beizi (i.e. short-sleeved beizi) before the term beizi eventually came to refer to a long-sleeved beizi in the Song dynasty, and referred as dahu in the Yuan dynasty. The banbi is in the form of a waistcoat or outerwear with short sleeves, which could either be worn over or under a long-sleeved ruqun. The style of its collar varies. It can be secured at the front either with ties or a metal button.
