The coat was added to the costume by Jang Bahadur Rana, a prime minister of Nepal in the 19th century.
[2] Daura Suruwal is a modern variant of the Tapālan (Nepal Bhasa: तपालं) which has been the traditional clothing of Newar men.
It used to be traditionally worn as men's common costume consisting of a long shirt called tapālan with tight fitting trousers known as suruwā (Nepal Bhasa: सुरुवा:).
A waistcoat or a coat along with a cap called tapulī / topī (Nepal Bhasa: तपुली) would complete the garb.
[11] The Nepalese Prime Minister Bir Shamsher Jang Bahadur Rana wore the Daura-Suruwal on an unofficial visit to the United Kingdom in the 19th century, which popularised the costume further in Nepal.
