Having tried both this and the original Mon Guerlain EDP, I can hardly tell the difference. Very good inspiration for a fraction of the price.
Very natural, authentic lavender scent, with some vanilla and woody notes blended together smoothly. It's certainly to my preference, but I'd only recommend it to people with that general taste.
The only disappointing part is that it doesn't last very long in my experience, but I have no qualms with merely applying it on again when it fades.
