The answer is...no we don't. I don't understand why designers design such outfits in Pakistan. The usual outfits are salwar kameez, lengha and sarees for parties....usually those that are not revealing.
I am sure it is to impress Pakis in America and make them think Paki styles are modern and cool. But guess what? No Paki or shall I say very very very few think so. I asked my cousins if they would wear such styles and they looked at me like I was stupid. They said things like "My Mom would kill me!" or "You know that its haraam so why would I wear it? Not even if someone offered me million dollars to do so." So yea, I doubt regular everyday women wear these revealing styles in Pakistan. Its probably just models and actresses at high-end parties..
