The Real Thing: A model poses on Friday at the Kate Spade show during New York Fashion Week. In The Knockoff Economy, Kal Raustiala and Christopher Sprigman argue that copying major designers is good both for the industry and for consumers.
During New York Fashion Week, designers will present looks that you might find in a department store next spring ... or, as knockoffs at Forever 21. That's because copying fashion designs is perfectly legal — and that's a good thing, if you ask Kal Raustiala.
Raustiala is the co-author of a new book called The Knockoff Economy: How Imitation Sparks Innovation. He talks with NPR's Renee Montagne about who copies fashion designs, why it's legal and how copying ultimately benefits the consumer and the industry.
