I often get enquires from people asking what is the best clothing to wear in Luxor or in Egypt generally. They are generally asking from the point of view of being respectful in a Muslim country. I tell them down to elbows and knees and up to neck. However I never understand why people don't cover up from a health point of view, especially children. Australains realise the dangers and their children have long sleeved swimsuits with sun protection.
