"It wasn't "Villager" dresses that became obligatory but the black headscarves. This would be their distinctive mark, one that would differentiate them from non-Saudi Arab women. More or less they were worn, though sometimes only around the neck like a scarf, as one might wear on Les Champs-Elysees." (p. 146)
(Picture taken in 1981 - a very few Saudi women, usually those with "wasta," still wear their mark of distinction in the same way today)
