Why wear it? To gear down from all the leather and segue into a slightly more forgiving frame of mind. Also, there's not much of it left in the sample vial. The angels do take their share, don't they?
What does it do? Sets the teeth ever so slightly on edge. Between its prickly aldehydes and the mild rasp of sandalwood in its drydown, there's this jewel-like spring-green note that summons April even while dour Autumn soldiers onward.
How do I feel? A bit wistful, wearing this today. It's so out of season to both my mind and my nose, that I almost feel protective of it-- this tender green shoot about to feel the bite of winter frost.
