Introduced in 1992, Thierry Mugler's first scent, Angel, was a game-lchanger in the fragrance world. The bold, brash bottle (it was blue! and star-shaped!) looked like nothing else in the department stores. And the scent itself was unapologetically sweet and rich, with notes of vanilla and chocolate. (It's considered to be the first "oriental gourmand" fragrance.) The ad campaigns, initially photographed by Mugler himself, were also iconic in their own right. The house's creative director, Christophe de Lataillade, oversaw all the campaigns, including the 1992 ad starring Estelle Lefébure hanging off the edge of a Manhattan skyscraper and the 2008 ad starring a secretly pregnant Naomi Watts. De Lataillade (who translated French romance novels before he was hired as Mugler's assistant 25 years ago) is still with the brand, and this year, they're celebrating the scent's twentieth anniversary.
