Here are the folks I worked with, which I post to give a sense of the variety of styles of dress. Women wore hijabs, or they wore stylish Western clothes. Men wore dishdashas with and without headgear, or they wore business casual. The two groups hold name cards are the teams I coach.
The bottom picture is our gala dinner at the JW Marriott, in which all the men wore traditional clothing — some of them uncomfortably — because it was a fancy event. (At the center table is the US ambassador and other distinguished guests.)
