As far as i know, most of people know vintage cat eye glasses because of audrey hepburn who wearing cat eye glasses in her movie "Breakfast at Tiffany's." that very attracting. That happens about through the 1950s and into the 1960s. Besides, the sex symbol Marilyn Monroe also like to wear cat eye glasses. And the cat eye glasses give her more attracting look.
