I got to try JHAG Not a Perfume long ago, and had no particular feelings about it. On my skin, it smelt kind of chemically clean. Almost like pool chlorine, in a good way. I was looking for a scent that had great longevity but not a lot of sillage, since I was trying to feel clean during my long shifts and not disturb the people I worked with at the same time. I then tried the Superdose version because the original one didn't last long on me at all (maybe I went nose blind to it).
This perfume in particular reminds me so much, and I mean so much to the late dry down of Light Blue. It's clean but sharp, and a bit musky. The best facet of this scent is its longevity. It lasts till the next day, and even more in clothes.
I enjoy the original one more (even though I'm pretty neutral to that one too), but I can see this one on someone that LOVES that clean, summery, musky dry down from Light Blue. Not for me, since I was expecting something almost transparent, and this perfume's quite sticky.
