Wear the fez with a pinstriped double-breasted suit, and classic Persol sunglasses such as the ones Marcello Mastroianni wore in Fellini's "8 1/2." It's Constantinople circa 1964. Quite chic.
Ah yes, the King Farouk look. Reminds me of the beginning of Diamonds are Forever ("Hit me."). I suppose if I could get away with it, I'd wear a shit-eating, dog-with-two-dicks grin like President George W. Bush since Wednesday morning... But surely Marcello wore the Persols in La Dolce Vita rather than 8 1/2, no? <EDIT: my bad, forgot about fez, it's been a while since I saw 8 1/2>
