P.S. that's one of the really positive things about Chanel, they've kept their line almost entirely intact since day 1. Even their reformulations preserve the integrity of the originals as much as possible.
And my own minor rant, I don't think guys here care, but a lot of people get up in arms over reformulations. There are two main reasons for them as I understand. One is regulations around allergens. Personally I'm all for this. I don't want to give anyone an allergic reaction, nothing smells that good for me to do that.
The second is around cost or availability of raw materials. If you can't source the original materials, you have to find a way to 'make do'.
On the other hand, cheaping out, just to increase profit margins is a bummer with a lot older fragrances, especially cheapies. Sometimes I'm sure it's a necessity but others, well....
Anyway, Chanel is one of the best when it comes to keeping their brand image intact. It's still amazing to me they even make Antaeus, yeah I'm weird and love it. Also not a big fan of the Allure line at the moment, just not to my personal taste, but I'm sure sales on that line are ten fold more than a funky beast like Antaeus, even if it has been a bit tamed over the years. So props for that
