I am a patchouli fan and I tend to buy bpal that has patchouli in it. I usually tend to go for the more "sweetened" patchouli scents like Silkybat, Incipient Madness, and Lady in Black atmo spray. But Sumatran Red Patchouli is a very different patchouli smell to me since it is a single note. It is earthy but not "dirty". The earth is more of a woodsy smell. It is more of a dry, warm, woodsy, relaxing patchouli. Very meditative and comforting.
The initial hour on my skin is very woodsy and has very strong throw. After about three hours of wear, it is a more close to the skin scent. On my skin after 3 hours it has morphed to be a sweetened patchouli scent. The slight sweetness reminds me of Lady in Black. The longer I wear it, the softer and sweeter it gets. Both stages (woody and sweet) of Sumatran Red Patchouli are gorgeous.
