Balhae (698–926 AD) imported a lot of various kind of silk and cotton cloth from the Tang and diverse items from Japan including silk products and ramie. In exchange, Balhae would export fur and leather. The clothing culture of Balhae were heterogeneous; it was not only influenced by the Tang dynasty but also had inherited Goguryeo and indigenous Mohe people elements. Early Balhae officials wore clothing appeared to continued the Three Kingdoms period tradition. However, after Mun of Balhae, Balhae started to incorporate elements from the Tang dynasty, which include the "putou" and round collared gown for its official attire. Male everyday clothing was similar to Gogoryeo clothing in terms of its headgear; i.e. hemp or conical hats with bird feathers; they also wore leather shoes and belts. Women clothing appears to have adopted clothing from Tang dynasty (i.e. upper garment with long sleeves which is partially covered by a long skirts and shoes with curled tips to facilitate walking) but also wore the "ungyeon" (Yunjuan; a silk shawl) which started to appear after the demise of the Tang dynasty. The Ungyeon use is unique to late Balhae period and is distinctive from the shawl which was worn by the women of the Tang dynasty. People from Balhae also wore fish-skin skirts and sea leopard leather top to keep warm.
