The US version of Thierry Mugler Le Parfum coffret has already started functioning, and I only happened to notice it today. You can finally browse the website [link no longer working] to read the descriptions of fragrances and inspirations in English as well as use the online form to purchase your coffret. The set of 15 fragrances will cost $700. Please see more information on the project created in the collaboration between IFF perfumer Christophe Laudamiel, Christoph Hornetz and Thierry Mugler team here.
Please see my review of the fragrances. Also, the December issue of Allure features the story on Le Parfum coffret.
