The Oscar-nominated actress was the first black woman to wear cornrows on TV during her stint on the series "Roots." She continued to showcase this and other natural hair care styles on the cover of magazines, which countless celebrities such as Rihanna and Jada Pinkett-Smith have recently brought back into style today.

"Angela Davis was at the forefront of the 'Black Is Beautiful' movement with her emblematic Afro," says Bernard. Started in the 1960s, the movement sought to dispel the idea that black features like textured hair, skin color and facial features were inherently ugly by encouraging black men and women to avoid straightening their hair and bleaching their skin. Davis' Afro became a loaded symbol that supported her political activism and involvement in the civil rights movement.

The plunging necklines that you saw in "American Hustle," you can thank Bianca Jagger for. In the '70s, Jagger effortlessly stood out in any crowd, thanks to her penchant for bold accessories, unique dresses and skill at executing Tomboy style in a flattering way. Her wedding dress choice says it all: Instead of a traditional white gown, she opted for a suit blazer and wide-brimmed hat when she tied the knot with Mick Jagger.

"Diana Ross really put the idea of a diva on the map by adorning her slim frame in exquisite gowns," says Bernard, referring to Ross' consistently show-stopping looks. Her long lashes and larger-than-life hair also elevated her to style icon status. During the recent '70s style resurgence, we saw the same voluminous look on the 2013 runways. Today, Solange Knowles is often seen paying a spot-on homage to the Supreme's look.

While many designers are artists that function behind the scenes, Carolina Herrera is known both for what she sends down the runway and her stunning personal style. She first made the International Best Dressed List in 1972 and was later inducted into its Hall of Fame in 1980 -- a year before she launched her own fashion line. Herrera's eye for fashion has influenced the country for years. She's the woman responsible for dressing first ladies from Jackie O to Michelle Obama in elegance.
