I wear a gele on my head when I am doing African cultural programming. Sometimes I wear a gele at other times just to cover my head from the cold or just because I feel like it.

A gele is a Yoruba {Nigeria, West Africa} word for a headwrap that is made by tying and tucking a rectangular piece of material in different ways. The cloth might be the same pattern as the rest of your outfit, or its pattern and color{s} may just compliment that your {African or Western style} outfit.

HERE is a page that shows examples of different gele/head wraps.
