Tanja Wessels, an advocate for sustainable fashion joins us for a chat this week on Insincerity. To give you an idea of her commitment to a sustainable future in the world of fashion, she has not purchased a new piece of clothing in over four years. Although we know nothing about fashion, we chat with Tanja abut the "sustainability movement" as a whole, and try to learn how to sift out the real movers from the posers.
