true and I suppose the type of kurta and color, fabric etc plus cut matters. like a really loose kurta and shalwar with a button up vest kinda gets a little strange look since its all neat and clean to the waist and then loose.
It has to be said that depending on physique, fabric, colour choice, people can really do things that
I know a couple of older gentlemen who do a white kurta shalwar with a blue blazer, and it looks good, I dont think I can pull it off but they do it and make it look good. one of these gents has for years been wearing tweed sports jackets with heavier material kurta shalwar in winter and one of em afghani woolen hats and suede shoes and looks very dignified, I have not had the guts to try it.
