Oh, yes, I forgot the coolie hat! (I also believe Illya wore a cap while pretending to be a chauffeur in one ep, but I couldn't figure out which one. He also might have been wearing a turban when he was onstage in Off-Broadway, but I'm not sure as I've blocked that scene from my memory XPPP)

Napoleon is impressively unselfconscious about his attire (such as that awful sweater in your icon...wearing it on their date, no less! XD)
