As sure as falling temperatures, flying phalanxes of geese and golden leaves herald the arrival of autumn, so too does the appearance of a flock of new luxury fragrance introductions. Like clockwork, each fall brings forth dozens of launches in a bewildering array. This season there were several fairly significant events in the category, with Louis Vuitton re-entering luxury fragrance for the first time in almost 30 years; make-up artist Charlotte Tilbury launching her first scent; ditto Alexander McQueen, architect Philippe Starck, and shoe designer Christian Louboutin (the latter two actually launched three new scents at once, and sadly none of them smell like new shoes fresh out of the box). Tom Ford introduced Orchid Soleil; Aerin Lauder debuted Tangier Vanille; and SJP (that’s Sarah Jessica Parker, for the uninitiated) launched “Stash,” her new fragrance, which she describes as smelling “like a sweaty European man.” OK, then. Moving right along.
