I own both the EDP and the EDT, but I should put the EDP on my swap list because the EDT is so much better. The EDT will always be in my collection. In fact, I'm in the process of cutting my wardrobe down by at least half, but Hanae Mori H.M. EDT is a keeper. The EDP isn't bad, but it's too heavy for its own good in my opinion. The lighter concentration of the EDT seems to allow more separation of the notes - especially the citruses. The citruses and the jasmine float into the air while the amber, tonka and vanilla cling to skin. I feel like the EDP wears more like a gooey blob.
In theory, H.M. has a chocolate note, but really, it's more of an impression of chocolate being made by those other sweet notes. So don't expect a chocolate scent. Instead, expect a citrus cologne style scent mixed with a gourmand, though the mixture of the two keeps it from being a gourmand scent overall. It's citrus & florals in the air with sweetness on skin. For me, that's a winner.
Hanae Mori H.M. is fun. I wear 3 sprays of the EDT and get 10 hours from it. I've gotten ridiculously good feedback from dates. You can find this one online for around $20 or $25. But even if it cost $100, I'd still recommend it.
