I love this scent. It grows on you, I had heard all about the hype with Bianco Latte but I also heard people talking about Celeste.
This is a floral gourmand, you can smell the violets and there is a sweet powdery opening but then it starts to develope and you are left with a sweet caramel/milk biscuit scentthat is Bianco Latte.
If you want something different and complex then this is for you, however, this is not blind buy safe. I would order the sample first and see if you like it.
As for sillage, yep! I left a scent trail! Longevity on Celeste is about 8+ hours. I ordered the sample for Bianco Latte and I actually preferred this. It was still sweet, and this is definitely a sister to Bianco Latte but it's different, I loved how it was absolutely unique. I'm planning to buy a full bottle of perfume but I wanted to order some more hard to reach samples from here first. I love the variety of samples you can't find anywhere else.
