She's a beautiful woman. In revealing western clothes she will draw more attention from western men and my impression would be that she is open to dating in the western style. If she mostly wears traditional clothing, it would suggest to me that she is not open to dating western-style, or at least is not desiring attention from people she does not know well.
I think she looks gorgeous in the traditional. The only modern one I like is the jeans and scarf look. The others look trashy. The black dress looks like something out of Pretty Woman and she looks like she rolled out of bed and threw on some clothes in the black and white one. She looks much more classy and beautiful in the others
