Well, I hesitated to reply because my answer is so vague. But here goes anyway: I tried SMN Zagara last summer when we visited Aedes, but I was really underwhelmed. It was not memorable and I had to look at my own wardrobe to see that I had given it a mere 2 stars. Unfortunately I did not take notes on why I didn't care for it. But there are lots of reviews of it on makeupalley.com, if you want to read others' opinions.
I have not found any orange blossom more to my taste than L'Artisan Fleur d'Oranger, which many fault because it is short-lived (true, but it lasts longer if you get some on your clothing-- and it is glorious while it lasts!) Yes, it is very pricey, but 15% off and free shipping from beautycafe.com made it more affordable for me.
