For me 'l'instant magic' was a blind buy.I was attracted to the pink colour of perfume.It seemed to me girly but when I smelled it things totally changed.Although it's not a niche perfume I think it can be compared to a niche perfume.At first all you can smell is white flowers with lemon but after a little while it turns to a powder heaven-not a baby powder /talc powder perfume, but a baby soft perfume with an etheral vanilla, an almond or better bitter almond clean/musky perfume, that lasts for hours without being heavy.It is just like you are in the middle of a sweet-powdery cloud so light that everyone will notice.
Actually, Guerlain is considered niche. Yes, I was surprised to learn this. Guerlain is considered niche because all they make is perfume aside from a few cosmetics now. If they also made clothes and shoes, they would be considered designer.
