Kourtney Kardashian's complete style transformation: From statement boots to chic LBDs

From baby bumps to statement suits, Kourtney Kardashian has been through one of the most iconic style evolutions to date. Known for mini dresses and for pairing wide-legged trousers with mini crop-tops, the oldest sister of the Kardashian Klan is arguably one of the best dressed.

The reality TV star and mother of three came on the scene in 2007 and has been one of our style muses ever since. Whether she's rocking a sexy LBD or mastering the art of styling OTK boots, Kardashian's off-duty style is just as chic as her red carpet moments.

Some of her favorite designers include Yeezy (of course), Givenchy and Saint Laurent.
