The following advice applies to women when visiting historical sites: Short skirts/shorts, revealing tank-tops or other types of potentially “provocative” clothing are not recommended. Unfortunately, this type of dress attracts unwanted attention and can be looked down upon, given the fact that Egypt is a primarily Muslim country.
In general, women should wear long sleeves and dresses in Cairo and cities/locations other than Luxor, Aswan and Hurgada, where more comfortable, less conservative clothing is more accepted because of tourism. When in these locations, it is still good to adhere to having a shawl to cover up when needed.
The above advice does not apply to Nour El Nil cruises. You are welcome to wear whatever you would like while on the cruise, including bathing suits, bikinis, tank-tops, etc. Our staff is used to serving western clients and are not offended. Our staff is completely respectful and most of all, we want you to be comfortable. After all, Egypt can be quite hot at times!
