Trust me this was exactly my train of thought when I saw the scene... When she's been wearing ultra modern dresses all this while, why suddenly so embarrassed coz of the lack of a dupatta??? But I guess its just that she didn't expect to see Armaan then n there and we all know Armaan is having a strange effect on her these days so it must be that...
Lekin baaki cases mein Bhagavan jaane... or should I say CVs jaane ke how and why the heroines are so overcome with embarrassment when they are without their dupatta when the way they wear it does not serve its purpose in the first place... Rem the Holi party scene when a drunk Sid takes off Ridz dupatta in an attempt to dance with it (Since Ridz was so unwilling to dance with him)??... Even Ridz was feeling all awkward ....
I guess I am more into wearing the dupatta the proper way and then if it got misplaced I would be embarrassed but yeh log tho pehenthe hi theek se nahi, tho tension ki kya baath hai???? Shayad dupatta jis tarah bhi pehena jaaye is a symbol of your modesty, even if it serves the original purpose or not.... Thats the only reason I can think of 😊
