My reply might be considered off topic, however...
Individual parfums are liked / disliked based on our own experiences, so i suggest you try by parfum houses, instead of 1 particular parfum from a niche house a person might like or suggest to your post...Some from the below may not be considered niche - ex Chanel Exclusifs, but then again, these are relatively sought mostly by parfumistas and not the regular crowd...

Maitre Parfumier et Gantier
Dior La Collection
Mona di Orio
Maison Francis Kurkdjian
Etat Libre d'Orange
Comme des Garcons
Nejma (not a niche IMO, but has a relatively cheap & wonderful Aoud series)
