I had the opportunity to buy Christian Dior Eau Noire last July while I was in Paris, but I knew it was also getting a re-release. The SAs at the Dior boutique didn't know if the re-release would be global or if it would be available individually or only in their limited edition box of three (with Cologne Blanche, the only Dior exclusive that had actually been discontinued and not just made exclusive to Paris, and Bois d'Argent). They also didn't know what sizes it'd be available in if it was made available outside the limited edition box. I had been wanting Eau Noire for a very long time--it's really unique--but one thing that had kept me from buying it was the fact that it was only available in 250ml, which is A LOT given that it's not really the easiest wear. There was also the matter that it was only available in Paris--at least, at the time.
Anyway, I took a gamble and waited, instead buying Leather Oud, which I was sad to have never picked up before it was made exclusive to Paris. The gamble paid off. Not only was Eau Noire made available globally, but it was even made available in the States in the hard-to-get 40ml size. They're still saying it's a limited edition, though, so I figured it would not be a good idea to wait too long to snatch a 40ml for myself.
