Cover your legs! The quickest way to attract lots of undesirable attention is to wear short skirts or shorts, since legs are considered more erotic than breasts. Slip-on shoes are essential– it’s culturally appropriate to take off your shoes when stepping on any carpeted surface or mat. Pretty much anything else is acceptable. In Dakar, the capital, people tend to dress up more than in the US; older (30+) women in traditional clothes, younger women like they’re going clubbing. I didn’t choose either of these options; I just wore what was comfortable since I knew I would be easily identifiable as American no matter how I dressed. But no shorts or short skirts!
