The red lip: An American classic

German actress Dietrich defied typical gender roles of the by portraying strong female characters on-screen in films like Morocco and Shanghai Express, and her bold crimson lip made just as big of a statement.

It's impossible to speak of red lipstick without mentioning Marilyn Monroe, whose trademark rouge lip was as synonymous as the icon herself. While the jury is still out on whether or not gentlemen prefer blondes, there's no denying that Monroe's signature pout continues to influence the '50s-inspired beauty looks of today.

The late starlet's impressive film resume and colorful personal life may have made more headlines than her beauty looks, but Elizabeth Taylor knew the power of a bold red lip worn with confidence. "Being true to myself has always served me well," Taylor told InStyle in May 2010. "Be original, and be authentic."

Horne was famous for her roles as an actress, dancer, and singer—namely hits like "Stormy Weather," and "I've Got Rhythm." Between her perfect coiff and iconic ruby lipstick, Horne's beauty look certainly deserves a standing ovation.

The "At Last" singer showcased a vermilion lipstick on the cover of her eponymous 1962 album that was as strong as her own showstopping voice.

The rumor that redheads can't pull off a scarlet lipstick? Not true! Ann-Margaret broke the sterotype when she paired her fiery strands with a glossy red lip—plus a ruby manicure to boot!

Talk about pretty in punk! Blondie's "Heart of Glass" single pushed the boundaries between the disco hits of the '70s, while offering a preview of the new wave trends of the '80s—and Debbie Harry's red lip followed suit. The saturated hue paid a nod to Harry's rocker-chic persona, while the glossy finish gave the look a modern edge.

Forget the "less is more" mantra: In the '80s women pushed the limits with hair and makeup, which was certainly the case with Whitney Houston's bright eye and bold lip at the 1986 American Music Awards. "I love lipstick. I've got a lot of it!" the late singer told InStyle in January 2010.

In the '90s, fashion and beauty took a grungy turn, and the red lip wasn't excluded! Wine-toned crimsons like Drew Barrymore's became commonplace, flattering fashionistas and rocker chicks alike.

Perhaps as a nod to one of the original blonde bombshells, Aguilera channeled her inner Marilyn at the 2006 Grammys with her scarlet lip and platinum ringlets.
