Cairo is not an ultra-conservative city, though there are acceptable ways to dress that one can notice when he\she arrives. For men, pants are more acceptable than shorts, although shorts are not culturally forbidden. Woman should avoid bearing their shoulders or wearing skirt or dresses that expose their knees. This goes for the summer as well. Of course there are areas where one will notice that the dress is a bit more liberal. Students are encouraged simply to observe customs. When visiting mosques, or religious areas in general, the woman’s arms should be completely covered.
