For me, it's partially psychological - I don't want to smell like the herd. I am a unique little snowflake, afterall Actually, there are a fair number of places where you can get niche perfumes, especially if you live in LA, NYC, Paris, or London - Neimann, Saks, Barney's, even Sephora will have some niche scents. The "nichiest" store in the US has to be The Scent Bar in Los Angeles. You can feel the tug on your wallet a block away. Niche doesn't always mean better, just rarer and most of the time costlier.
