They are looked down upon in general and feasted on by sight, most countries advise them to dress modestly, but arent too strict on the rule, except Saudi Arabia where you have to cover youself up with a black ankle length cloak and seperate headress if you step out anywhere from your home, same in Iran but a bit more relaxed.
Surprising though that a supposedly ultra conservative nation like Saudi Arabia have rather relaxed uniforms for their female airline cabin crew, but in Iran which was ultra liberal at one time and is still less conservative than Saudi Arabia, have very orthodox uniforms for Iran Air crew, of course SV's uniforms uptil the 80's were designed by top European fashion houses and featured knee length skirts and half sleeved tops as well.
I believe in Oman even men are not allowed to wear shorts and tank tops in public.
But then in Harrods you cant even enter wearing cutoff's, even if its topped witha designer shirt, blouse, Tee etc. weird.
