I absolutely love this. It enhances other fragrances and leaves a soothing calming fragrance on its own. It's a perfect summer extra. Love it!

I love it

It literally Smells like I dont know what and lasts forever

The perfect fragrance enhancer for fall and winter

It adds the most sexy warm smell to a lot of the perfumes that I already own. It smells so wonderful layered with Jo Malone's Wood sage and sea salt and helped with longevity. I have seriously never had my perfume last all day long. Cannot wait to repurchase this one over and over again.
