The abaya is a cultural thing, it stemmed from the requirements of an Islamic dress code: loose, modest, and subdued. Almost all of the neighboring Muslim countries have some form of the abaya that the women wear. From Iran to Egypt, the long overcoat that constitutes the burqa, colors its wearers with the flavor of their culture; the mesh veil in muted colors dots the alleys of Afghanistan, with the tailored cuts of stark blue, purple, and green overcoats gracing the streets of Jordan. Saudi Arabia’s signature happens to be black; the black abaya. It is merely their interpretation of a loose, modest, and subdued covering.
