Clothing in Cambodia is one of the most important aspects of the culture. Cambodian fashion differs according to ethnic group and social class. Khmer people traditionally wear a checkered scarf called a Krama. The "krama" is what distinctly separates the Khmer (Cambodians) from their neighbors the Thai, the Vietnamese, and the Laotians. The scarf is used for many purposes including for style, protection from the sun, an aid (for the feet) when climbing trees, a hammock for infants, a towel, or as a "sarong". A "krama" can also be easily shaped into a small child's doll for play. Under the Khmer Rouge, krama of various patterns were part of standard clothing.
