Yesterday, I joined “Project Runway” finalist Korto Momolu on an episode of “The Stream,” an innovative multimedia show on al Jazeera English. The topic? Cultural appropriation. Turns out that Momolu has gotten a lot of heat for incorporating African designs and textiles into her work . . . despite the fact that she’s from Liberia. I was part of the mix in order to clarify some of the ownership rules around cultural remix practices in fashion.
