The skirt style at 3:03 by the dancers look like the Khmer apsaras style which I have not seen anyone wear that style anymore, very sad lots where lost by Khmer Rouge era. I see the latest style of people recreating the apsara skirts and it looks very stiff and uncomfortable not like the one in this vdo which look so comfortable to wear. I think the skirt in this video is soft and relaxed fit, very wearable and comfortable in Boran times for khmer.
