The GHO is a Bhutanese male ethnic clothing. The wearing of the "GHO" for men and "KIRA" for women is only a small part of the "Driglam Namzha" (official dress code of Bhutan). The GHO is a knee-length robe tied at the waist with a "kera" - hand-woven fabric belt. Bhutanese people began to wear the GHO in the 17th century. Today, the local men use this attire for formal occasions; the government representatives are obliged to wear the GHO for work.The Bhutanese Gho is an adaptation of a traditional Tibetan garment called a Chuba or Chupa, with added cuffs. A chuba is a long sheepskin-lined coat made of thick Tibetan wool worn by many of the nomadic peoples of high altitude in the cold mountains of Tibet.
Size: Bhutanese GHO doesn't go by a definite size chart, it's mainly based on estimated body height and waist size
