i found that topics about arabic make up and dress are rather popular and inspite of that many sites suggest information about these topics.people all over the world still have questions about arabic look. i have something also to suggest you but it is only according to my own taste of cause that based on muslim culture and arabic traditions. the question how muslimah girl can dress in western country to look oriental and same time appropriate to that society she live in. i think next pictures will give you clear idea of that what i am talking about. Just must say that woman in the pictures is brazilian and these pictures shooted from a movie where she played a morrocanian muslim woman who need to share her life between Morrocco and Brazil.
Note1: on these photos she is in Brazil but when she is in Morrocco she dress niqab and loose black abaya outside her house.
Note2: Ilike her look here and same time judge it be cause acc.to shariah(islamic law)dress of woman must not be see through and her neck and ears must be covered. But always remember that people are weak and a lot of muslim women doesn'e cover their hair anyhow so anyway that one who cover only part of her hair is better cos make less sins than that one who doesn't cover her hair at all and that one who cover compleatly her hair is the best one and deserve hasanat (rewards)because she doesn't commit a sin then that one who cover only part of her hair.
