Most women (mostly Saudis but also women from other countries) wear this:
Most don't wear gloves though!
Some doesn't wear the face veil.
I and many other foreigners just wear a black abaya without the veil. No, no one is wearing any other color on the abaya, only black. Some might be decorated with pearls etc but the abaya itself is black.

Most men wear this(mostly Saudis I assume):

Most foreign men wear "normal" clothes such as jeans and shirt.

Well it doesn't get much more interesting than this. Sorry :)

And ye, both pictures are from google. I didn't take them myself.
