I finally tried it. I've never actually worn it before, only sniffed and dismissed it as yet another old aldehydic menace like No. 5.
I applied a few drops to my wrists and neck, and nearly scrubbed it right off. Those nasty aldehydes almost drove me to my knees, but just as I was passing out with the image of a WWI gasmask-readiness poster as my last coherent thought, the chemical topnotes dissipated sufficiently for me to regain full conciousness...
Gas! GAS! Quick, boys! -- An ecstasy of fumbling,
Fitting the clumsy helmets just in time...

After that, I had to leave for work.
While driving, the middle & base notes creeped forward, the warm vanilla note for which Shalimar is famous hummed up from a dim filament to radiant full glow. A different chemical-musk-greenish middle note also appeared with the vanilla; cheap shampoo filled the air, and until it dissipated I couldn't shake the feeling I hadn't rinsed my hair out completely. This is the note co-opted into copycat spinoffs and background scents for toiletries, much like No. 5 has been. Evidently, this is the cheapest component of the scent. One of those cheaper scents, such as B&BW Warm Vanilla Sugar, fly by these notes, zooming directly to the vanilla. But Shalimar is on a train, and is concerned with the journey itself, not the mere vulgarity of "getting there".
