Mr. Belimom has some more info - then I'll drop the whole thing about the way Muslim men dress...
He worked in the Middle East for about 15 yrs. He was briefed on the customs (such as how he could never cross his legs the way Western men do because it would mean the bottom of his shoe would be facing someone, which is the ultimate insult) but he learned many of them from years of traveling to and living all over the Middle East: Egypt, Saudi Arabia, Oman, Kuwait, UAE. He was just saying that - as far as he knows from his *cultural* observations - there is not much in regards to requirements for men's clothing as there is for women's. There is more governmental control - such as Saudi men being required to wear the Saudi headdress and traditional clothing while in Saudi, but that when he was on flights heading to Saudi, the men would board in the Western clothing they had worn and change into traditional clothing before landing in Saudi.
He had other observations but I think you get the point and I feel now that this point has officially been driven into the ground. I'll stop now.
