Daura suruwal is cool but not as convenient as modern clothes. To think of it, do you think Daura suruwal is really indigenous to Nepal as much as Kachhad is? It looks like an imitation of Rajput/Mughal clothing from the medieval times .... remember, that those times Nepali kings have been known to send "saugats" to those Mughal emperors and seek their blessings.
