In Northern Thailand, the Old Kingdom of Lanna Thai, traditional folk dress of the culture can still be seen in everyday use. On Fridays, staff in many government agencies (the Post Office or Municipal Office is an example) wear a "Northern Thai Style" shirt (properly called "Moh Hom") which their ancestors of centuries ago created as daily work dress. Likewise, many pedal samlor or tuk-tuk (dtook-dtook) drivers regularly wear the Moh Hom while women wear the female equivalent coupled with a slim; ankle length skirt called a Pha Zin. Of course, at special times of the year when a parade is a feature of the festival, just about every local will be seen in his or her very best ceremonial Moh Hom and Pha Zin.
