At the series premiere of Keeping Up With The Kardashians in 2007, Khloe rocked the signature Kardashian hair - long, dark, flowing locks - an understated dress, and low heels. It's definitely not the Khloe we know and love today, but we all had to start somewhere.

At the season two premiere party of KUWTK, Khloe's style had already started to evolve into something a little more daring: a bandage dress, sexy, strappy heels, and sideswept bangs.

A bodysuit, body-hugging skirt, and leopard print accents? That's definitely more like Khloe, and even though the outfit looks a little bit dated nowadays, she still totally rocked it.

Rocking dark eyeliner, sexpot curls, and a tiny mini dress, by 2009 Khloe definitely wasn't afraid to channel her more sexy side.

Sleek, layered hair and a body-hugging bandage dress? Sexy without being too over-the-top, this is a Kardashian look all the way.

At the 2011 People's Choice Awards, Khloe hit the red carpet in a totally new look for her: bright auburn hair. She was practically unrecognizable, but the new do was a gorgeous contrast to the steel gray of her gown.

At the launch of the Kardashian Kollection in 2011, Khloe showed off two staples of the Kardashian look: shiny ombre curls, and a daring print.

Part of developing your personal style is experimenting, which is one thing Khloe has never been afraid to do, judging by this look. Rocking a drastic nude lip and a fairly subdued outfit while attending the X-Factor season finale in 2012, Khloe looked practically unrecognizable.

Sexy white dress that shows off your curves? Check. Perfectly styled waves parted down the middle? Check. A killer shoe and handbag? Check and check! From her hair to her feet, this look is totally Khloe.

For the iHeart Radio festival in 2013, Khloe showed off her edgier side in a leather two-piece and her trademark ombre hair. Plus, need it be said? That side braid is everything!

When Khloe stepped out with slicked back hair and a dangerously low-cut dress with a high-slit skirt last year it was totally unexpected, which is probably why it became one of Khloe's most iconic looks.

2007-era Khloe K is history! While promoting her book, Strong Looks Better Naked, Khloe showed off a long blond bob, glossy lips, and a show-stopping neckline.

While attending the Yeezy season 3 runway show earlier this year, Khloe linked up with her estranged husband Lamar Odom, and struck a pose in skin-tight jersey and glamorous faux fur in nude tones.
