Alien was created in 2005 by Dominique Ropion and Laurent Bruyere as the second fragrance for the House of Thierry Mugler. Alien is based the composition on three main lines: warm, white amber in the base, woodsy notes in the heart, and sunny Indian jasmine in the top. From the website, a description of these three facets:

RADIANT REVELATION
Alien is radiant, illuminated by Sambac Jasmine from India: a magnificent tropical flower whose delicateness contrasts with its powerful fragrance. A spiritual offering, a sacred promise of femininity.

MYSTERIOUS REVELATION
Alien is mysterious, enhanced by the sensual notes of Cashmeran Wood: both enigmatic, characterized by its bold and musky fragrance, and exotic, warmed by an intense sun that intoxicates the senses.

ENVELOPING REVELATION
Alien is enveloping, enriched with White Amber. MUGLER has created a modern and timeless white amber: a note as soft and cozy as white mohair.

Offered are 15ml refillable flacon stones.  Perfect for the purse.
