Welcome, Butterscotching, so glad you found us on the Internet and decided to join in. Please stay.
Here we go.
If The Perfumed Court is your friend (or wanna-be friend) and you want to find your fragrance fast and easily, splurge and order to wear a few times -- need more than 1ml vials though! -- from the following list: Ormonde Jayne Osmanthus; Parfum d'Empire Osmanthus Interdite; The Different Company Osmanthus, Ineke Evening Edged in Gold, Keiko Mecheri Ume (not Osmanthus, as anticipated and I personally do not do KM's musk) -- there must be one of the osmanthuses for you.
If you are prepared to wait and be picky about what you are going to wear, you might find what you need on eBay (there is also a forum right here on BN called Fragrances Wanted -- you can request a sample). These are not niche, but IMNSHO, not inferior to the list above:
-- La Perla Parfum Prive (and this is a secret -- do not tell the whole world now!) -- creamy, silky with woods and resins in the base, enticing, a winner by all accounts including the balance between the price and the quality;
-- Ungaro Desnuda (this is another secret) -- velvety smooth, warm and sexy scent with an added bonus of the brush it comes with, playful and sweet;
-- Hanae Mori Magical Moon -- mystical osmanthus blooming at midnight by a delapidated castle located on the pond with croaking frogs and frightful black birds -- woody notes might be too expressive of the scenes they have witnessed;
-- Yves Rocher Cantate -- Oriental fruity, very October-appropriate, celebrating nature's harvests in shades of merlot and claret, lush and unexpectedly light;
-- Isabel Derroisne Ame Toscane (I wore it last week).
