My top three for something that's niche and has good sillage and
is a favorite of mine:
Michael Storer - Winter Star ( best sillage and longevity of anything I've tried - and smells nice, too! )
Ava Luxe - Midnight Violet ( the opposite of a shy violet fragrance )
Parfum d'Empire - Cuir Ottoman ( Cuir d'Iris and Knize Ten are stronger leathers, but this is my current favorite. )
Being fickle, my favorites could change tomorrow.
