>> Prepare to be a little mesmerized. Chanel's process for making its iconic, chain-lined tweed jackets is a multitiered operation that requires a lot of people — and a lot of attention to detail. Patterns get cut for each jacket in the fashion house's atelier, then a team of seamstresses cut and sew individual pieces of the jacket, then sew it together and add all the finishing touches. Most of the work is done by hand, and it's hard not to be captivated watching it happen. Perhaps that's why Chanel is releasing a new book about the jackets, The Little Black Jacket: CHANEL's Classic Revisited by Karl Lagerfeld and Carine Roitfeld, this Fall. In it, everyone from Sarah Jessica Parker to Alice Dellal is captured wearing the iconic piece. We'll have a behind-the-scenes look at the making of the book tomorrow, but for now, check out how the jackets are made below.
