for what it's worth, here's my two cents:
There are other ways to look classy and appealing without sleeveless dress. Culturally we are conservative and jholmole shobuj hatkata jama reflects poor choice (p'aps wardrobe dept. to be blamed?)
She does speak good English but no need to be wannabe-Bollywood or Radio Foorti like RJ. (here comes chinaman_f)
So Salwar Kameez would've represented BD culture well and shown artistic taste instead of Western clothes.
