I used to have different views regarding chadar and scarf but I have changed my views now because I have realised that hijab should be worn according to the culture, for example, in Saudi the culture is black burqas but in India women wear the most colourful clothes.
In the West, chadar is not practical and you will stand out amongst others if you wear it, a scarf with modest western clothes is quite common and acceptable here and people won’t notice you much.
In Pakistan, I guess a big chadar is the best type of hijab to be worn, I’ve seen that people respect chader clad women more than niqabis in Pak.
