Those of you who are not already in possession of the November, 2005, issue of Threads magazine, which had for a cover story a step-by-step exploration of the inner workings of the Paris-based brand's famed unstructured, quilted, cardigan-style jackets might find this video useful. It pretty much covers the basics.
There was a documentary I can't find now on the dying art and industry of couture. They have this little old lady out in a backwoods cottage somewhere who's maybe the only person on earth who can do this special kind of braiding Chanel does with their jackets.
And there was this kind of hilariously snooty countess-type lady. Rattling around this big marble mansion with her little dog, wearing couture all day every day.
