In Bhutan there is a traditional national dress prescribed for men and women, including the monarchy. These have been in vogue for thousands of years and have developed into a distinctive dress style. The dress worn by men is known as Gho which is a robe worn up to knee-length and is fastened at the waist by a band called the Kera. The front part of the dress which is formed like a pouch, in olden days was used to hold baskets of food and short dagger, but now it is used to keep cell phone, purse and the betel nut called Doma. The dress worn by women consist of three pieces known as Kira, Tego and Wonju. The long dress which extends up to the ankle is Kira. The jacket worn above this is Tego which is provided with Wonju, the inner jacket. However, while visiting the Dzong or monastery a long scarf or stoll, called Kabney is worn by men across the shoulder, in colours appropriate to their ranks. Women also wear scarfs or stolls called Rachus, made of raw silk with embroidery, over their shoulder but not indicative of their rank.
The practice may have originated in a Celtic festival, held on 31 October–1 November, to mark the beginning of winter. It was called Samhain in Ireland, Scotland and the Isle of Man, and Calan Gaeaf in Wales, Cornwall and Brittany. The festival is believed to have pre-Christian roots. After the Christianization of Ireland in the 5th century, some of these customs may have been retained in the Christian observance of All Hallows' Eve in that region—which continued to be called Samhain/Calan Gaeaf—blending the traditions of their ancestors with Christian ones. It was seen as a liminal time, when the spirits or fairies (the Aos Sí), and the souls of the dead, could more easily come into our world. It was believed that the Aos Sí needed to be propitiated to ensure that the people and their livestock survived the winter.
