sōi shussui 曹衣出水

Ch: caoyi chushui; also sōibyō 曹衣描. Lit. "wet-clothing drawing." A style of figure painting in which clothing appears to be wet, clinging to the human form. So called because the clothing of the Buddhist statues from Sogdiana (Jp: Sōkoku 曹国), an area of Central Asia, appeared to be sticking to the bodies of the figures as if they had just come out of water. 

The Chinese painter Cao Buxing (Jp: Sō Fukō 曹不興, act. 3rd century, Three Kingdoms period) is said to have painted in this manner as is the Chinese painter from Sogdiana, Cao Zhongda (Jp: Sō Chūtatsu 曹仲達, fl. ca. 550-577). The technique is one of the 18 types of figural portrayal *jinbutsu jūhachibyō 人物十八描.
