No, stripping off is not OK.Roughly 90 percent of Egyptians are Sunni Muslims, so conservative dress will make life much, much easier for them and for you. What works on a private hotel beach or in a high-end Cairo club will absolutely not cut it at the Giza Pyramids, your local koshary joint, or—god forbid!—the taxi home.Long, loose, opaque clothing that covers all the key areas (shoulders, chest, belly, upper arms, and legs to the knee) is the way forward, while many find sunglasses help avoid unwanted eye contact. Women will want to bring a shawl or scarf to cover their hair while visiting the mosque.Heading to a hot Cairo club? Do like the locals do and hire a driver for the night.
