According to this article in the October issue of Vogue, the above jacket was the inspiration behind the A/W 07/08 Chanel Haute Couture collection.
"The riding jacket hung in the Chanel atelier on Rue Cambon in the weeks before the show. Too miniature to be worn by anyone—size 0 must have struck Bourbons as positively enormous—it served as an example of exactly what good design can achieve: beauty and utility that retain their relevance for centuries."
The construction of the jacket looks very complicated and the result is amazing. (Click the image the see the beautifully detailed seams & construction).
