This website shows the evolution of the shape of the Chanel No. 5 perfume bottle (and very interestingly, its lid), from its original 1921 shape to 1986.
And Wikipedia's entry on Chanel No. 5 describes the evolution of the scent, and how Coco Chanel decided on the final perfume. She explained:
I want to give women an artificial perfume...Yes, I really do mean artificial, like a dress, something that has been made. I don't want any rose or lily of the valley, I want a perfume that is a composition.
