San Diu women wear an indigo headdress, tunic, and skirt with a belt. The tunic has a high collar, plain hem and no buttons. Inside the hem they sew a white cotton facing. Usually, the women also wear double-breasted indigo coats lined with white cotton. Older women wear their tunics with the left flap over the right, while young girls wear it the opposite way.  For modesty's sake they wear an undergarment resembling a bra, since the tunic is not buttoned.  Women's belts are light green, indigo or violet, and the ends hang to the knee. Women's skirts are made from two or three pieces of cotton,  not sewn together, worn calf-length. They are attached only at the belt and flap freely. This unusual style gives rise to another name for this ethnic group: Vay La, which means "skirt resembling a leaf."  They often wear leggings, usually of a neutral color.  They like jewelry, often wearing necklaces, bracelets, earrings and chains.     

San Diu men wear clothing similiar to the Viet, but for ceremonial occasions they wear white trousers, a black tunic and a muslin turban.
