Among extra occupations, weaving was once well developed but it has declined now, because the Ro Mam usually buy mass produced goods sold in the market. Ro Mam women usually wear jupes and shirts with short sleeves. The jupes are made from coarse cloth without decoration and fall down below their knees. According to old customs, young people have four to six of their upper teeth filed for aesthetic reasons. Nowadays, they do not follow this practice.
Women like to wear earrings, bracelets and necklaces made from glass beads.
The village of the Ro Mam is called a de headed by an old chief who enjoys the trust of all the villagers. Each family comprises 10-20 persons of various generations who have blood ties. The couples live under the same roof, but each nuclear family forms its own economic unit. Each house has a corridor running the length of the house. The central part of the house serves as a reception area for guests and a place for common entertainment for all nuclear families.
