Language/Wolof/Culture/Appearance-and-dress-code
Dressing up is extremely important in Senegal.Whereas the way you dress can be considered a reflection of personnlities (hippy, conservative, fraternity-sorority type etc.) In Senegal, the way we dress is usually considered an indication of the respect we have for others around us. Observe and use local work partners as models for how to dress because it mainly depends on your environment and the people you are interacting with. But, make some pretty traditional clothes for special occasions in your site, people we feel really happy and it’s a sign of integration. Nonetheless, people are really tolerant because they know, you come from a different culture with a different dress code.
