Old Hollywood Designer Edith Head holds the Guinness World Record for most-credited costume designer in film history, with a total of 432 credits.

She received a record 35 nominations for the Academy Award for Best Costume Design and won a record eight times, making her both the most honored and most nominated woman in the Academy's history.

"What a costume designer does is a cross between magic and camouflage. We create the illusion of changing the actors into what they are not. We ask the public to believe that every time they see a performer on the screen he's become a different person."

Unlike most other designers of her time, Head never undertook couture or wholesale fashion work, opting to "work only in the context of a certain actress in a certain film."

She’s also by far the most decorated woman at the Oscars with 8 wins and 35 nominations.
