I do see a distant relationship to Organza they have somewhat the same background texture, but there is a big difference in strength. This one is very subtle: It takes a lot of concentration to even smell it. It opens with a light floral / citrus. I cant place the particular floral the honeysuckle / lily of the valley mentioned in the pyramid sounds about correct. Then in the middle it switches to an extremely light white floral I get primarily jasmine with a shadowing of vanilla. The drydown is mostly vanilla. I dont get any of the wood mentioned in the pyramid.
First Light is soft and light to the point of disappearing. I do (barely) smell the entire fragrance and its movement and it is a pleasant sheer floral but I really dont determine any sillage, just a skin scent, and not a very remarkable one at that. Weak, nice but bland, short-lived: that about sums it up.
