When these elected officials meet in the parliament for a session it does not look nice or professional to show up in different kinds of outfits like they are all attending a fancy dress fashion show. I think this issue was also covered in the thread
Check Out These Assholes?

Anyways, but what really amazes me is why should an elected official from the Himalayan region or Terai region not give up their usual outfit from either region so that the dress is appropriate for the unique weather seasons of Kathmandu. In the Capital city, neither the Madhise dhoti can withstand the severe cold nor the bakhkhu from the Himalayan area can bear the summer heat. If the officials cannot even reach a consensus on a professional code of outfit and language then how in the world are they going to agree on the slew of debates they will be have to overcome in the days to come?
If wearing Daura Suruwal during office hours for the elected ones is too much a hassle then formal dress code  like pants, shirt and coat for men and a sari and blouse of selected hues for women should be employed as a requirements.

Also the news media should only conduct interviews in English or Nepali (whichever is appropriate) whether it's for newspapers, television or internet media outlets and no matte where the venue or region is.
