Just got this in the mail today, and I love it! I've had the perfume oil for a couple of months after discovering it on a trip to Seattle. The oil definitely has a deeper profile to it, however, the spray gets deeper as it dries down. Overall, however, I would say that the scents align extremely well and layer nicely. I wear this scent everyday (Olivine Atelier, if you're ever looking for an ambassador...) which is new for me as I get frequent headaches so often cannot handle having something on everyday, especially something sweet. However, this scent is different - it is subtle yet strong. The vanilla is deep and sultry rather than overly sweet. It's a very mature scent, especially for a vanilla fragrance. I highly recommend this perfume and the perfume oil as well. Still, if you're like me and want to smell fragrances yourself before buying a full bottle, I highly recommend the samples - particularly the moon perfume collection set so that you can choose which one you like best!
