Okay, I finally got down to sampling Floris 89.
In a way, it does have a similarity to Habit Rouge edt. Its got a similar vibe. That doesn't mean they smell exactly alike, but I also would not say they are night and day either. Perhaps it is the floral notes. But I do feel the vanilla and opoponax start to dominate more into the dry down of Habit Rouge edt. Whereas in Floris 89, it gets to be more of a woods and rose.
Both are quite nice. But I think Floris 89 starts to smell "off" or funky on my skin after a while. Habit Rouge edt ( in vintage formula) is awesome to me. The current gets a bit on the sweet and powdery side.
Maybe its French vs. English here and down to what style and vibe one prefers. Hope this helps Hamp
