Formerly, the niche perfumes were defined by limited retail distribution, a criteria set by The Fragrance Foundation (FiFi), the non-profit, educational arm of the international fragrance industry. But it has all changed.
[...] The evolving fragrance market makes the definition moot, said Chong and he suggested this perspective: “Did it start as a perfume house? Heritage is a limiting factor as some niche brands have longer histories while others like Byredo are younger but no less distinct.” He added that another big tell is the scent narrative. Niche fragrances have more depth and authenticity because they reflect the inspirations of the perfumer, his lifestyle or travels for instance.
