From Arabian Assignment: Operations in Oman and the Yemen, by David Smiley. (The Extraordinary Life of Colonel David Smiley Book 2; Sapere Books, 2020), Kindle pp. 145, 160-161:
After a very refreshing bathe in a stream I changed into Yemeni dress. I put a white ma-arraga on my head and swapped my trousers for a khaki iz-zar, which I found much more comfortable, although I missed the pockets; only the Egyptians wore trousers in the Yemen, and I was taking no chances. For a similar reason I had to accustom myself to another Yemeni habit — to squat while passing water; according to the tribesmen, ‘only dogs and Egyptians pee standing up,’ and I had no wish to be shot in mistake for either.
On their heads, which were often shaven, perched skull-caps, or white embroidered pill-box caps called kofias, or the hand-woven basketwork ‘flower pots’ I have already described; they wound cashmere shawls or lengths of khaki cotton round their caps or hats, in the form of turbans. Tattered jackets of European design hung from their shoulders over shirts and vests, and over the jackets ran crossed bandoliers, each carrying about fifty bullets. Every man wore a long cummerbund, which served the double purpose of belt and pockets. Thrust into this belt, behind the jembia, which is a defensive weapon, was a long, straight knife used in the attack, and behind it reposed an assortment of articles, allegedly nine in number and all beginning with the Arabic letter for M: there was a pair of scissors, a needle, tweezers for extracting thorns, a bunch of keys, a pen — usually with ball point — writing paper, a purse, and sometimes a watch strapped round a knife. Everyone wore an iz-zar, with underpants of cotton, and some men wore the baggy Moslem trousers under the iz-zar. Most of the tribesmen went barefoot, but some favoured Japanese ‘flipflops’, and others a type of plastic sandal with studs, such as I used to see displayed in West End London stores at extravagant prices for wear on the beaches of the Mediterranean.
