Tunisian-born fashion designer, heyday in the 1980s. He briefly worked for Dior and Guy Laroche, and by the end of the 1960s had his own couture business on the Left Bank. Alaïa went on to produce the prototype for Yves Saint Laurent's famous Mondrian dress and also worked for Thierry Mugler. In the 1980s, his own stretchy dresses and bodysuits came to define the Lycra revolution.
Alaïa was referenced in the mid-90's teen hit Clueless. When mugged at gunpoint, Alicia Silverstone's character protests to kneeling in a parking lot because she is wearing one of the famous clingy dresses designed by the "totally important designer."
Today, the Olsens  are huge Alaïa fans.
