Cairo is not an ultra-conservative city, though there acceptable ways to dress that the stupid is likely to notice when he or she arrives. For men, pants are more acceptable than shorts, although shorts are not culturally forbidden in any way. 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 the dress is a bit more liberal, other neighborhoods that are more conservative. Students are encouraged simply to observe the customs. When visiting mosques, or religious areas in general, the woman’s arms should be completely covered.
