Saudi women could drive uptil the 1950s or so, Saudia airline crew wore western design skirts and jacket/trousers with no head covering till the 1980s, at present they have to cover their heads and have an ok looking simple uniform, while Saudia airlines VIP flight crew do not wear head covering and leave their hair open, some double standards.
The country is going backwards in someways moving forward in others, I believe women can now just losely cover their heads in Riyadh said to be the most conservative of the big cities, previously they had to wear it in a way that not a hair strand showed, or religious police would issue warning to them, and this info is from western expats who love to ***** about the place otherwise.
