Niche  

In perfumery, niche classification refers to fragrances that are produced by small, independent, and often artisanal perfume houses that focus on creating unique and high-quality scents using rare and expensive ingredients. These fragrances are typically not widely available in mainstream stores and are marketed to a more discerning and sophisticated clientele who seek out fragrances that are different from the mass-produced designer perfumes. Niche fragrances often have a more complex and nuanced composition, and are known for their longevity and sillage (the trail of scent left behind). They may also have a higher price point due to the use of premium raw materials and the limited production runs.
